Ekipi

"There exists secrets outside our realm that our eyes could never see. I worked long and hard to try and uncover these secrets, to tear down the barrier that kept us from discovering them. Unfortunately, as you can obviously see, being here and all, that didn't go quite well. Nope. Not at all."

- Ekipi briefly explaining the motives behind the creation of the Dark Arts Ekipi (作家, Ekipi) is an ancient, but very well-known figure in the history of Earth Land, being heralded as the Horror Author (作家恐れ, Sakka Osore), the person who created the now revolted and feared Dark Arts, as well as the equally feared monsters of Horror that come from being devoured by said Dark Arts, along with an entirely seperate dimensions that she now "rules". The result of these creations also made Ekipi known as She Who Forged Darkness (同氏誰偽闇, Dōshi dare Nise Yami), further cementing her as a legendary figure, who gave rise to an abundance of monstrous creatures and evil Mages as a side effect of her desire to uncover all the world's secrets.

Predictably, Ekipi now resides in the Dark World that her Dark Arts created, where she is effectively the "God" of it and the Horrors, and could freely traverse between worlds, as well as having complete control over each and every Horror, even the humanoid ones who have retained their minds and souls.

Trivia

 * The name Ekipi was made up by the author when trying to create a name that would reference the initial "H.P." for H.P. Lovecraft.
