This is a precursor to =Nyxen's prize art. Technically this fulfills the stipulations of the request, but I have something else planned for the actual prize. This stallion is in the prize as well, but he will be partially blocked so you will not see all of him in it (hence I'm showing him off here).

If you look at the line drawings in the background of this, you will notice both the stallion and his mare (both part of the actual prize piece) but without their manes, so you can see the design below the masses of hair.

And if you want to know the reasoning behind the name, you will have to wait for the real prize piece, and I will explain the catalyst part then.
