I just re-read the first TPB, and read some spoilers on wikipedia (tired of waiting for Vol 2 TPB).
It seems Darth Krayt is A'Sharad Hett. Can't believe I didn't figure it out. It was pretty friggin' obvious. Darth Krayt and the face tattoos (which you see when he takes off his Tuskan Mask in one of the Clone Wars comics).
When's the next TPB supposed to come out?
