Here have we another Arkanith: Kendris.
As you might notice upon the way this picture is done, it's an older picture (before I had ink pens).
The Arkanith are seperated in three castes. Worker, warrior and priests. And each caste is also seperated in three fractions. The priests are seperated in light priests, dark priests and psi priests.
Here is Kendris, from the dark priest fraction.
