Now before I tell the theme of this picture, the figure on the right is a Tracker of the mutant clan of the Forsaken nation, and the figure on the left is a "Trickster" for the Forsaken Nation.
Trackers are large, physically and mentally strong melee units that act as agents of psychological warfare. However they have serious abandonment issues and absolutely cannot stand being alone.
Tricksters are charismatic and social sharpshooters that often play mind games with thier opponents, and are adored by thier lowers.
Trackers LOVE Tricksters for thier social nature and often defend them with thier lives.

Now the picture is strangely constructed on purpose, because it was drawn by a Tracker. Trackers sketch figures representing thier companions on stone tablets they carry around, and these rough scetches can be very emotional. The figures in this picture have no eyes or faces because it represents the mourn the one drawin' this one felt, the Trickster most likely died and his Tracker drew this to symbolize his loss and sorrow.
