Alright, I guess I'll throw this out to the others as well. Ariel just gained access to magic that likens her to a newborn spirit. As such she could be summoned and contracted (so long as she's in spirit form). Not going to define how to summon her as I want to see what you guys come up with. But everyone should notice the unusual appearance of a new spirit in the world. Since she's a blank slate in the way of spirits I might have her change slightly based on who summons her. Not sure. Take it or leave it, only one can get a contract.

Looks like Gideon, Gabriel, Michael, Andrea, and Amelia could potentially summon Spirit Ariel. Correct me if I'm wrong.

You's wrong about one thing.  Andrea's magic is Rock Menagerie, which allows her to bring rock monsters to life rather than summoning existing beings.
