Greater Than Games GTG73618 Spirit Island: Feather & Flame Expansion

Q: I just got horizons of spirit island. is this expansion compatible with my version?

All spirit island content is compatible, however the jagged earth expansion is required for most of the new concepts and tokens. 2 of the spirits in this pack are fine without JE and would work with horizons, the other two not so much. If Horizons is your first set, I'd recommend base Spirit Island next.
