Nommo

Actual Universe
The Nommo are mythological ancestral spirits (sometimes referred to as deities) worshipped by the Dogon tribe of Mali. The word Nommos is derived from a Dogon word meaning "to make one drink." The Nommos are usually described as amphibious, hermaphroditic, fish-like creatures. Folk art depictions of the Nommos show creatures with humanoid upper torsos, legs/feet, and a fish-like lower torso and tail. The Nommos are also referred to as “Masters of the Water”, “the Monitors”, and "the Teachers”. Nommo can be a proper name of an individual, or can refer to the group of spirits as a whole. For purposes of this article “Nommo” refers to a specific individual and “Nommos” is used to reference the group of beings.

This cephalopodic species once coexisted with the Trilarians but left after the War of the Depths. In contrast to peaceful Trilarians, Nommo are highly radical and militaristic. Nommo believe they are descended directly from the "Old One", the god of the first Ichthytosians who brought them wisdom and consider themselves as "children of god". Nommo will engage in holy war against whatever might deny them their birthright. They have strong hatred toward Trilarians who still lay claim to what the Nommo consider "their" homeworld. Despite being militaristic race, Nommo aren't very good when it come to ground combat - not unlike Trilarians.
