Commission of a greater demon (Gilrandree) and two lesser ones (Asterion and Varke), by waori Original at http://www.furaffinity.net/view/12233950/
I really like how this came out, and especially the expression on Asterion's face; to me it reads like a question, "Are you sure this was such a good idea." Of course, if you go around summoning demons, you have to expect to get things beyond your ability to handle.
Interestingly, I've come up with a bit of a story to go with this, tying into a forthcoming piece by Kaji.
