I think in the very least Poseidon and Ursula will be immortal merfolk with some magic on the side. (Which will be a deity to me if they are worshipped, which they are)

I think Ariel and Ursula don't have much in the way of story unless Ariel met Ursula after she returned to the sea after meeting Snow. Ursula has a past with Hook, which I'm sure will cover most of it. I think they will film most of the stuff in a building underwater or on a rock, I mean land right above the sea.
