I've always loved the idea of possession so I thought what if I made a character that's possessed by something. How can I pull this off without breaking AL rules?
My initial idea was to reskin the flavor text of the Warlock class. I don't know if this is allowed under AL rules however. The goal is for the character to be possessed by some other entity and for the entity to gain control over the character as they level.
For reference I've never played D&D before and am currently borrowing some materials from a coworker. I currently have the PHB, Volo's Guide to Monsters, and SCAG on hand.
Summary: (warning: still depressing)
the character is friends with some kind of spirit (unspecified) and find herself traumatized by certain events the spirit decides to help her in the worst way possible first by showing her illusions to make the world seem like a happy place and when that fails replacing her and sealing her away to "protect" her.
