I am now obsessed with the STO Cosmic Horror AU because it just fits too well. Hakeev already was literally a cosmic horror villain. He fanatically worshiped ancient alien gods that he did not understand, and sacrificed his own people in his efforts to summon them so they could establish a new order.
The only difference between Cosmic Horror Hakeev and regular Hakeev, is Cosmic Horror Hakeev wears 1920s meanswear and a monocle.
I also tried to evoke a bit of Mike Mignola-style shading for this one, given that he’s synonymous in the public conciseness for comic book cosmic horror aesthetic these days.
