"Anatomy of a Monster"

Wolverine discerns that Maggott’s slugs weren’t responsible for the murders in Salem Center and heads for the N’Garai cairn near the mansion. He’s joined by Beast, Marrow, and Cecilia Reyes, while the rest of the team tracks down a distraught Maggott. After finding him, they’re suddenly teleported to the Ukraine. They enter the nearby N’Garai cairn and are reunited with the rest of the X-Men inside the N’Garai’s dimension. They soon learn that the murders were actually committed by Pilgrimm, a member of the N’Garai’s former slave caste, the Ru’Tai.The race is powered by the Eye of Kierokk, which Reyes manages to accidentally destroy. The X-Men rescue the Ru’Tai’s human captives and return to Earth. Pilgrimm, however, disguises himself as a human and escapes.
