Shuma

Shuma is an old white whale and the arch-rival of the former-Khan, Hubbub. At some point in the Fifth Age, Quin a powerful Sea singer, using the Elder Horn, forced Shuma to attack Hubbub's village, and was successful in destroying the majority of it, leaving only two survivors: Hubbub, and the Old Man of the Sea. Hubbub proceeded to stab Shuma in both eyes in a fit of rage, rendering her completely blind, and then lost his leg. Since then, he has continued to hunt Shuma seeking revenge.

Recently, Shuma set out to destroy New Heritage in an attempt to seek revenge on humanity, whom she regarded as responsible for the loss if its eyes. Hubbub set out to stop her, and proceeded to be eaten by her. In her belly, he used his "Sea Monster sense", which he had learnt he could use to use to talk to sea-creatures from the Old Man of the Sea, and convinced Shuma that Quin was the one she should seek revenge on, and in gratitude, she vomited Hubbub out. Since then, she and Hubbub have become good friends, as she enjoyed her battles with him.
