Here are some concepts on entities that were never added to Apeirophobia but could possibly be added soon?
Attention user!
What you're about to see are official entities but weren't entities ever made. Everything here is real, but will most likely exist as a concept forever.
This skin walker wouldn't take the form of a person they killed, instead it would keep the appearence of a previous lost wanderer that died to the Assembley. It seems like a normal person at first but if it's far enough away from it's prey and wants it fast, it'll separate it's limbs as shown and gain a faster mobility speed.
The entity was never seen fully before, only by 1 person. It's unknown what it was or what it's motive was. It rarely appeared behind players at random intervals and would always disappear the second you got even the tiniest glimpse of it. However one person saw it fully before, they said they saw it fully for 5 seconds as it was reaching it's hand out for him, but disappeared before grabbing the wanderer.
Just a taller version of the partygoer but has hands and not the mouth hands, it also has pupils. But thats about it. Nothing special
This thing would be a sack that looked like it had a person inside. It would scream for help and wiggle around the more you looked at it. They say it only took 3 seconds before the voices got to you... What happens next, it's unknown. However it would always be found in vents hence the name.
The point of no return wanderer.
This titan was pure nightmare. Only been documented once and drawn. Not much is know but what we do know is that it is the smartest entity ever documented. It would make itself sound like it was somewhere entirely different from where it actually was. That's how it hunted it's prey. It has a searchlight as a eye, stay away from it at all costs. It's huge, even making the Titan Smiler look small. It's attacks were deadly, It would trap you and tangle you around in it's ribcage. if you died to it in Multiplayer, you would die and have to wait for someone to save you. If you died in singleplayer you would loose 1 life. It did a minigame, fail to do it in multiplayer 1 time and you died and lost 2 lifes. You get 3 chances in singleplayer, fail, you lost 2 lifes.
Though smaller than the Roaming Ribcage it was still very deadly. It mainly relied on camouflage to hide from unsuspecting prey. Though it had some parts where it was exposed to it would sometimes give away it's location. Rule #1: always watch your surroundings here. Water... Water slows it down.
Since patch 15 The Orison has been added to Apeirophobia, featured in the revamped Level 15 (Ocean of the Final Frontier)
