Mius

A mius (Latin singular assumption from mii), de jure an aldus is a subspecies of human predominantly present in the Moricounien Federation. They share lineage with mourabiteaux however mii are more advanced in terms of expression with caveats.
==Details==
Mii are as tall as normal humans compared to mourabiteaux. They share the same regenerative capabilities with mourbs, but can only communicate audibly compared to mourbs, who normally communicate silently or at least literally on a different frequency. 
They share the genetic diversity normal humans take for granted.
