Balacaenata

Balacaenata are large bioluminescent whale-like beasts with a tail and flipperwings. Though peaceful, they are large and capable of slamming and ramming into things, dealing quite a bit of damage. Balacaenata are capable of flying in the skies or swimming in the water below.

Balacaenata are friendly enough that they allow other creatures to ride on their backs, so long as they refrain from causing any harm.
