So I have a question. I'm thinking of apping a pair of OCs - the two of them are spirits who reincarnate into multiple worlds together and retain memories of their past selves. Basically, the presence of each other is the only constancy in their various lives and they are compelled to seek each other out in new worlds. Because of this, they are very close to each other and it would be very difficult to play them separately, as their identities are built upon being one half of a whole. If played in-game, it's likely that they will stay within vicinity of each other and rarely be away from one another.

I can app them from two canon points, one where they have separate bodies and another where they have combined together to escape a curse. Can I app from the first one? It doesn't quite fit the 'possession' rule so I thought to check.
