Tartaros

Aaand here is the primordial god of...yes, you've guessed it! Tartaros! XD
Tartaros was considered the god of the stormy pits beneath the earth. He also was considered something of an anti-sky, being a solid dome under the earth, just like Ouranos was above. His name later became synonymous with the place of the damned in the underworld.
The similarity to Ouranos is intended. And I took myself the freedom to leave the tunic away! ;3
I can't believe that for the first time in my life I actually drew a naked guy and it looks good. XD
