If I remember correctly....
The left-most face belongs to Lord Xel. the creature in the upper-right corner is a Revenant, the figure in the upper-left corner is Zin, one of the human-revenant warriord that was given to Lord Xel for his coopperation, and the creatures in the lower-left and lower-right corners are Revenant Larva. Please tell if I'm incorrect on any of these.
