Old description taken from my Derpibooru account copied here.

Here’s my take on Egypt Horse. As usual, I’ll tweak and change her designs if I need to as I go.

So I don’t know much about Somnambula except that she’s one of the members of a group of 6 called the Pillars of Equestria and had to deal with Sphinx. I like Egypt’s history and unique figures and the humanoid gods they worshipped like any other historical time period did. I finally got to drawing her now.
I made a goof, she’s originally a pegasus.
