Y'AI'NG'NGAH YOG-SOTHOTH H'EE-L'GEB F'AI THRODOG UAAAH YOG-SOTHOTH , that which the crustaceans of Yuggoth worship as the Beyond-One, and which the vaporous brains of the spiral nebulae know by an untranslatable Sign, has been brought into our world. That foul conglomerate, offspring of the Nameless Mists, walks among us. It has broken two links in the chain by which it was bound. Three links remain. If it is YOG-SOTHOTH that breaks those links, then woe unto men. The party, having defeated Keeper Myre at the warrenstone vathouse, retreat some blocks away to an abandoned structure to nurse their wounds as night falls. The day was clear, yet the heroes can make out no stars in the sky. And the moon, which was near full and waxing a few days ago, does not rise at all this night. Elaryan gains consciousness, and identifies Keeper Myre's ring as a ring of counterspells , The journal is mostly in Aklo, but the last page is in Common, as it devolves into fearful ranting about how the Keepers should have heeded the warnings of the Pnakotic Manuscripts, how YOG-SOTHOTH will hunt them down one by one, and how it grows stronger with each kill. The Keeper himself is unconscious but stable, his hands bound and his mouth gagged. Everyone who played is awarded 1,800 XP. That includes a bonus for not slaughtering the Dark Creepers, who had been enslaved by the Keepers and who were (as you surmised) mostly terrified of what had been released.
