Nekton

Abstract
Considered by far the most benign and gentle of the ten Leviacons, Nekton is unusual in that he does not behave the same way as his kin. Rather than roam lone-wolf style, he spends his time guarding the island crystal beds near the Well, and the Well itself. Even for a self-titled guard dog of the most sacred spot on the planet, Nekton is still remarkably sweet-tempered. If approaching, the gentle giant will "inspect" the individual and, if approved, let them pass. How he might react to an individual he doesn't approve is unknown; no one has ever been turned away with anything more than the soft shove of a giant flipper."'I like to think of him as a big manatee. Just, y'know, with teeth. And tentacles.'"
