Morassia is a Class M planet, the fourth of six in the Euterpe sector. 64% of surface is covered by water.
Noted for its unusually diverse ecologies, it is ruled by three dominant sentient species, the Uk'les, Mnoi and Gumduemhai which shared a millennium of peaceful cooperation with main achievements in natural sciences. All three have a matriarchal system of tribal rule. Representatives comprise the Morassian Constabulary Government.
Morassians typically use the bones of the dead to make useful objects.
By 2365 the planet petitioned for Federation membership.
The Morassians constructed the Preserve encompassing three biotopes and a diverse array of species of the galaxy. (TNG video game: A Final Unity)
