Septaceans are large, tentacled sea monsters which inhabit the deeps of the oceans. Little more than flat black globs of slime, seven fleshy tentacles typically twitch beneath their shapeless underbellies, constantly searching for ships and other prey. Their beak-like mouths emit shrill, terrifying shrieks.
There are two known varieties of the squid-like septacean: red-faced and mudback. The most distinguishing feature of red-face septaceans is a patch of red around their two beady eyes. Mudback septaceans lack this crimson mask, instead taking their name from the mottled dark brown shades patterning across their backs.
One fearsome septacean is particularly famous for making its home in the dark depths of the Gulf of Nilakantha.
