A mysterious mark appearing on the walls of an apartment building unleashes an otherworldly evil that drives its tenants to madness and death. The story centers on five lonely tenants whose lives become inextricably linked when they discover this dark symbol. The entity born from the mark is a manifestation of intense emotions, feeding on love, hate, fear, and power. As the building itself seems to come alive, the inhabitants lose their free will, succumbing to confusion, chaos, and ultimately, a grim fate.

The 2008 Eisner Award-winning team behind this work has garnered significant acclaim for their previous collaborations. Mike Mignola, creator of Hellboy, has praised the storytelling as beautiful, effectively creating a sense of dread and supernatural menace. He further noted the narrative as smart, subtle, and genuinely disturbing. The collective reception highlights the story's effective build-up of tension and its unsettling atmosphere.
