Mucking around with alternate Initi designs. I got desperate and colored these with a mouse---not recommended.
The guy on the left is Tal Lune, a captain in the Initi Guard. He’s very straight-laced and by the book, and would lay down his life for anyone who needed it. The one on the right is Tritus Regem, and he’s the leader of the Initi military force (there’s another that takes care of things of religious significance and matters of the people). He is also Arko’s uncle. Very tough, hardcore guy. He’s seen a lot of action.
The older Initi get, the longer their tusks and ridges on the back of their heads and necks grow. They can also double in size. Another thing of note: under those fringes (which can move) is sensitive, highly absorbent tissue that help absorb oxygen from the air, as the atmosphere on Vesiphone is extremely thin. They’re like gills, but... not.
