The Mrlssi are one of the most intelligent species, probably second to the Obroans of Obroa-skai. Though their skin is green and their black eyes are large, similar to a Nautolan, the Mrlssi are diminutive and have large heads, compared to the rest of their bodies.
The Mrlssi created a planet-wide university on their homeworld, rivaling those on Obroa-skai, Coruscant, and Alderaan. The president of the university is the de facto planetary leader, for every Mrlssi is connected to the university. Because the university is at their fingertips, most Mrlssi have a strong educational background, as well as an open-minded view of the galaxy, even though few go out and travel.
