Opening Song - "Last Resort" by Papa Roach
The entourage, consisting of Earl, Qaplowski, Terofin, Orbod, Yelyah, Alyce, Interceptor, Balmora, and Ravenscroft, are sailing towards Stellarvania after containing Worldender in a "container" made of Essence.
Balmora confides in Orbod since she feels they're both "new" to something of such a grand scope of consequence. Also she tells him that she's been actively suppressing an ability she has to "absorb" Essence from sources around here (such as other users).
Interceptor talks to Earl (since they're both Alterbeasts and last were active in Everlong) since she can't talk to Alyce while she sails the boat
Yelyah talks to Terofin, reminiscing about Rygar (her lover that died) and being leaders (him being King of Stellarvania, her formerly leader of Cypress Hill)
Ravenscroft talks to Qaplowski about how her confidence in this is very low, because even though they have Worldender, Eonlypse is still out there and will want it
The group continues discussing betraying Ravenscroft since they still don't entirely trust her
After some more chit-chat, the group finally makes landfall on the same beach that Alyce brought them to last time (Season 1, Episode 3).
As they begin to dock and unload the Seahawk, they notice some black smoke in the distance where Castle Shimmer would be. A person comes running to them; it's a former member of Tazma's group and now member of the Castle Shimmer garrison, Brutus - "Take Me Out" by Franz Ferdinand
Brutus tells Terofin that Castle Shimmer is under attack by "everyone", at the least the Black Hole Sons and some "monsters" and that he's needed at once.
The threat that Liandri dealt with was taken care of, there were lingering effects that hindered their defense, allowing an ambush to happen
Brutus offers Terofin a "best path" into the battle. They decide to follow him
They arrive in front of the castle; Brutus heads off some enemies to allow the group to make a plan based on what they see in the battle
Surveying the battle, they're able to see some notable characters through the generic city guard and Black Hole Son soldiers
They see Tazma fighting in the thick of it
They notice a large fiery figure working their way towards the castle; Regnier - "Duality" by Slipknot
They hear screaming and gore everywhere across the field; they see a Metamorph, Kuros Tizrak - "Right Now" by Korn
Running away from her, as if he's leaving after doing something purposeful, is Thug Doug
In the distance, behind larger than usual Machineheads, they suspect it's actually Revelation - "Schism" by Tool
The group enters battle. Terofin attempts to attack Revelation but is useless. He makes all the known enemies notice them and what they have.
Yelyah attempts to attack Regnier can't make a dent. Balmora, looking for the groups direction since this is all overwhelming, she barriers Earl. Interceptor attacks Regnier and doesn't hurt him, but causes fire to spew out from him and enflame the battleground and others. He swiftly moves up in rage.
Terofin is engaged by Kuros and knows he's in a terrible position and must runaway. However Kuros manages to bite him, incapacitating him instantly.
Earl manages to hit Kuros with The Predator, wounding her in a significant way.
Meanwhile, Orbod tries to make the case Worldender invisible but fails. Qaplowski and Orbod make way into the castle regardless. Ravenscroft runs into the castle as well.
Alyce teleports Terofin out of the battlefield and back into the castle
Regnier sees the group run into the castle with Worldender and pursues them, summoning Lava Elementals near the castle doors next to Orbod and Alyce, and they attack Alyce. More fire engulfs the entrance to the castle now.
Revelation refocuses some Machineheads from the battle to instead engage the group
Orbod hits Regnier with a his earthly signature blast, wounding and knocking him down. Yelyah tries to take advantage and attack him while he's down. He deflects the blow but defending takes such concentration his Lava Elementals disappear.
Balmora tries to revive Terofin from across the flames and succeeds, leaving him back but still bloodied. Interceptor tries to attack Regnier as well but still fends it off. Noticing Kuros encroaching, she throws some Essence her way to distract her.
Kuros, angry at Earl and knowing he's not an easy meal, starts spraying acid from her pincers at everyone around her. It hits Orbod, Balmora, and Yelyah
Qaplowski manages to drag Worldender up into one of the castle towers to hide it.
Ravenscroft, perched up in a tower, shooting at Kuros, misses but kills one of the redirected Black Hole Sons instead. Alyce tries attacking Kuros but misses with all the hectic action immediately around her.
Regnier, filled with rage, unleashes a terrifying blast of fire around himself, affecting everyone immediately around him. Earl fails to compose himself and runs away from the battle until he gathers himself. He then walks up to the flames in front of the castle gate, concentrates them and blasts the fire towards Terofin, incapacitating him again.
The other redirected Black Hole Son takes advantage of the mayhem and shoots at Balmora, incapacitating her
Things look bleak for our heroes. Opposite of where the group entered the fray, more allies arrive. The Scientist with his army of Machineheads, along with Ranger-X and John "Warthog" Keyes. They engaged the Black Hole Sons. "Galvanize" by The Chemical Brothers
Orbod takes another shot at Regnier but misses this time. Rather a lot of earthly debris douses him and his flames, leaving him somewhat vulnerable.
Taking advantage, Yelyah is able to stab Regnier from behind, critically wounding him. Interceptor continues as well, and also critically wounding him and almost finishing him off.
Kuros continues spraying acid around her and incapacitates Orbod and cripples his right arm.
Qaplowski finally joins the battle and easily dispatches one of the redirected Black Hole Sons
Ravenscroft carefully aiming at Regnier, who's been tag teamed by Yelyah and Interceptor, lands a clean shot from her perched position and takes his head clean off. Alyce seeing that the battle is not going well, decides to teleport Orbod and Balmora next to Terofin and create a wall of Essence in front of the castle entrance. Black Hole Son soldiers try to break through the barrier but have no luck
The Scientist engages with Revelation in a "battle of AI's". John Keyes reaches out to Qaplowski, telling her she can use her Arc Glove to help The Scientist. The Scientist clearly gains an advantage on Revelation, causing sparks to fly out of him and also exploding the Black Hole Sons by the Essence barrier. However the explosions were enough to break the barrier. Then, a Sol'Ker appears on the battlefield, severely wounding Tazma and maiming Ranger-X immediately. "The Cyborg Slayers" by Dethklok
Yelyah shifts her attention to Kuros and as she attacks the Sol'Ker manages to sneak past them and get next Qaplowski. Interceptor attacks Kuros and misses but manages to use some Essence to pull back the Sol'Ker to impede his progress.
Kuros, hungry for more flesh, moves up to bite Qaplowski. She manages to hit her despite parrying, giving her an agonizing wound.
Earl attempts to attack the Sol'Ker but whiffs. As this happens, someone came back to help; Liandri - "Praise" by Sevendust
Liandri engages the Sol'Ker immediately and now locked in combat.
Qaplowski swings at Kuros but is countered and shoved to the ground, passing by and entering the castle itself.
Ravenscroft runs down the tower after seeing Kuros enter the castle and shoots at Kuros with the Phobos 12-SCG, wounding her but not slowing her down. The Scientist continues to win against Revelation as he slowly breaks down. The Sol'Ker manages to knock down Liandri and move closer to Worldender. Yelyah runs and uses all of her vials to revive Terofin, Orbod, and Balmora. Orbod immediately runs for cover and Balmora tries to heal those around her as much as possible. Interceptor tries to engage Kuros but she quickly makes her way up to where Worldender was hidden and finds it.
Qaplowski rushes to stop her, using all of her remaining strength to finish Kuros off and stop her from taking Worldender; she succeeds.
Earl picks up Liandri and mounts her on his shoulders like Master Blaster and runs her over to the Sol'Ker to get back into battle with it.
Ravenscroft runs outside to help. Alyce moves inside to the courtyard and tries to restrain the Sol'Ker but it phases out and reappears next to Interceptor inside the castle. The Scientist continues to win in his battle against Revelation, weakening him near collapse.
Terofin takes the opportunity to heal himself and his apprentice Orbod. The Sol'Ker moves into the room and sees Worldender pulled out from when Kuros discovered it. He attemps to break the case, but Qaplowski blocks the attack. Frustrated, the Sol'Ker blocks the door into the room with Essence. Liandri keeps up her pursuit of the Sol'ker, trying to break down the barrier. She's unable to but does startle the Sol'Ker. Yelyah is able to shatter the barrier, allowing Liandri to jump back into the action.
Orbod gets a higher vantage point in another tower. Balmora continues focusing on healing the wounds of Terofin. Interceptor attacks the Sol'ker. It dodges her attack but gives Qaplowski an advantage. She takes it, pressing the buttons on her Arc Glove REALLY HARD to help The Scientist in his effort to disable Revelation. It's successful, and Revelation is destroyed. The Sol'ker experiences a moment of interruption as it's link to Revelation is severed. Liandri takes advantage and is able to kill the Sol'Ker. However the Sol'Ker explodes and severely burns Liandri across her body.
The Black Hole Sons are now routed and the group is victorious in defending Castle Shimmer.
The Scientist approaches the group and explains that he met up with John Keyes and Ranger-X and after some collaboration they decided to go help Terofin/Qaplowki. Liandri spoke to Kaylyn and Lady Alanis and decided to go back and help Terofin. The Scientist is still interested in taking Ravenscroft as a prisoner. The group, after much deliberation, defaults to Terofin as they're in his Kingdom and denies his request. He accepts the decision. He than asks Qaplowski if she would accept him and his group of Machineheads to take refugee in Kontra. Ranger-X accepted his offer but knows for sure T'Mek would not due to the perception and strain it would cause on Kontra post-Omega Conflict. Qaplowski agrees for theme to stay in Kontra. The Scientist, John Keyes, and Liandri leave for Kontra.
The group decides to take a breather and regroup, healing everyone's wounds and restocking their inventory before heading to the Vortexergy to try and destroy Worldender.
They finally arrive at the Vortexergy north of Stellarvania. As they stare it down, Alyce says she thinks it has to be her to be the one to take Worldender into the Vortexergy since she can control chaotic Essence better than anyone else. After discussing all options. the group agrees to let Alyce take Worldender into it. Orbod suggests that maybe Balmora can help quell the Essence to help her get in. Interceptor voices her disapproval for having Alyce going into it. The group decides to test the Vortexergy's power by simply throwing a rock into it to see what happens. Earl throws the rock and it disintegrates as soon as it enter it. They know now Worldender needs to get extremely far into it so they have a chance. Terofin tries to predict what's about to happen and after some extra effort he's able to see that Alyce does get Worldender into the Vortexergy with Balmora absorbing Essence away from her. Any attempts by anyone else would lead to a disastrous end. Orbod suggests that they give Alyce the Warpcrawler in case she's unable to get out in time. Terofin agrees and gives it to her. Terofin also casts augment on Alyce.
Alyce wraps chains of Essence around the encased Worldender. She begins her walk in. Balmora walks up to it to being absorbing what she can. (The groups takes turns rolling for Alyce to make it further into the Vortexergy).
Alyce is making it through OK but Balmora is becoming engorged with Essence from absorbing so much. Orbod goes to quell the overflowing Essence in Balmora and does help deflect some to Orbod, causing various trees and vines to sprout up around him.
Alyce gets near the endpoint inside the Vortexergy. - "Famous Last Words" by My Chemical Romance
She succeeds; it's far enough in that Worldender will be destroyed. Balmora, overcome with Essence despite Orbod helping, faints. Alyce turns towards to the group and goes to activate the Warpcrawler to escape. However she faints as well and as the Vortexergy closes up, they lose sight of Alyce and the Warpcrawler lands in front of them.
