When the Dweller Awakes

"When the Dweller Awakes" is a story featured in The Adventures of the X-Men issue #4 by Marvel Comics. It is a crossover with the X-Men superhero team and the Cthulhu Mythos. 
==Synopsis==
The story begins with Scott Summers (aka Cyclops) encountering a group of N'Garai, who had escaped through a dimensional drift at Salem Center. Cyclops fights off a few of them before discovering the only house in the town that wasn't being attacked. Upon entering, Cyclops encounters a man named Erich Zann, who explains that the invasion was prophesied in the R'lyeh Texts (aka the Book of R'lyeh) and the N'Garai will awaken the Dweller-in-Darkness to bring devastation to the world. Although Zann refused to assist in ending the current threat, he informs Cyclops that there is a counterspell in the Book of R'lyeh that can banish all of the N'Garai, at the cost of banishing himself as well.
Cyclops heads to the N'Garai dimension and, with the help of his fellow X-Men members, manages to successfully retrieve the Book of R'lyeh. Unfortunately, it was already too late as Cyclops was unable to decipher the language and one of the Dweller's tentacles had already bursted from the ground. However, Zann comes back to save them, after his previous encounter with Cyclops helped him realize that the world is worth saving. After reciting the counterspell to banish the Dweller and N'Garai, Zann happily accepts his sacrifice as a form of atonement. Shortly afterwards, the Book of R'lyeh was also destroyed, crumbling into dust.
==Mythos Connections==
*In this comic, the Dweller is explicitly stated to be "a true offspring of Great Cthulhu". However, this was later retconned in the Official Handbook of the Marvel Universe A to Z Vol 1 #3, which states that the Dweller is "considered a worthy scion of the Great Old One Cthulhu, though no direct relationship exists".
*While introducing himself, Zann references the Hounds of Tindalos and Nyarlathotep. 
*The counterspell invokes the names of Cthulhu, Shub-Niggurath, Yog-Sothoth, Hastur and Dagon.
