The High Priestess of the Dreamlands is none other than Yog-Sothoth, for, Yog-Sothoth is the Gate.

Interpreting good old Yog-Sothoth was fun, as, what amounts to a cluster of bubbles, from HP Lovecraft's descriptions of him, didn't make for anything too interesting on it own. Figured that I'd just draw the part that you don't remember you see, due to not wanting to recall it. . . although, I think he turned out kinda cute. =P
