) Β She is. That alias is probably a good idea though, since the oc tag is implicative of cognitum (same person, or pony in this case).
Β One more note: While the characters of this species aren't Cognitum, they would, more or less, possess a part of her (in being partially possessed *by her* - hope that's not too confusing). So the implication of `cognitum` would be preferred, although it's not entirely necessary. Β Due to the character not actually being Cognitum, however, `oc:cognitum` can be either implied or not. Β Haven't read Project Horizons all the way through, but I do remember that being a present fact. :)
