I was there, where she promised she wouldn’t take me... A minute before I was locked in the library, and then I was there where she had gone with my body—in the place of utter blasphemy, the unholy pit where the black realm begins and the watcher guards the gate... I saw a shoggoth—it changed shape... I can’t stand it... I won’t stand it... I’ll kill her if she ever sends me there again... I’ll kill that entity... her, him, it... I’ll kill it! I’ll kill it with my own hands!
