Estella, Aurburn and Kana met as children and were childhood friends, as typical children do they create a faux teams and pretended to be huntresses

• Estella is the daughter of a prominent family in Atlas

  • Due to her status she is acquainted with Weiss

• Aurburn is the daughter of servants serving the Darlingtons 

• Kana often goes up to Atlas with Risa (her mother) when she has business up there.

• Kana is childhood friends with Selinos who is the adopted daughter of Pietro Polendina (Pennys Father). Kana would often go to her to make toy weapons for her, Estella and Aurburn.

However they get separated:

• Aurburn's family gets wrongfully framed for stealing from the Darlington Manor end is fired, resulting in them returning to Vacuo

• One day Kana and Risa go back to Mantle, but there's a Grimm attack where she sees Selinos captured and assumably killed, resulting in her and her family fleeing to (Haven or Beacon).

• Arrives when the anime starts (watches Ruby fight Roman)

• Starts off as a vigilante, fighting Grimm, White Fang, Roman.

• BEFORE the events of the Beacon Dance, Qrow spots Callie "the Vigilante" and arrests her. 

• He takes her to Ozpin, and Ozpin immediately notices that she's not from Remnant and gains an interest in her.

• He overrides her arrest and offers her a place as a student in Beacon. 

• Qrow doesn't really care, he goes off to do his own thing (Ironwood and Glyinda doesn't know that he's been around)

• Events of the Beacon Dance occurs 

• After separating Estella, Aurburn and Kana have their own teams formed by their respective schools.

  • Estella gets on with her team, but she doesn't like the overall attitude the Atlas students have on other people. In her team she's typically the one "carrying" them, though she wouldn't even verbally admit

  • After Selinos "death", Kana studies at (insert academy) and forms a team with fellow students however ever since the incident she is unable to form a strong connection with them. She's only with her current team because she has to be.

  • Aurburns Team? Found them too violent?

• They all are in Beacon for the Vytal Festival, throughout the festival they miss each others fights therefore doesn't realise each other is there.

• During the events of the "Fall of Beacon" they stumble upon each other, and when they fight against the Grimm they have perfect synergy.

• At some point they're all left defenceless, which is where Callie comes in with her "semblance", adding to the synergy.

After the Fall of Beacon, Callie takes them to the infirmary looking after them untill they gain consciousness. When they awaken they thank Callie, then recap and reflect on the fight.

• Callies like: "wow we really worked well together despite not knowing each other"

• Estella, Aurburn and Kana: "well."

After recovering they decide that they worked well together as a team instead of there current teams resulting in Team C.A.K.E. forming (inviting Callie along despite not knowing much about her).

They decided they will work together to protect everyone in Remnant resulting in them travelling together.
