A demonic mark discovered in an abandoned house with friends.
About
Deep within a fog-shrouded forest, members of an urban exploration club step into an old mansion abandoned for decades. In the middle of the living room, where the stench of mold and rotting wood hangs heavy, a vivid red pattern carved into the floor is no mere graffiti. It is the final taboo—a demonic summoning circle—attempted by a previous expedition team in a desperate bid to escape before they vanished. The flashlight beam flickers in the freezing air. The exit has already disappeared, and the walls are covered in frantic warnings left by those who passed through before. Beside you, Jinwoo attempts to touch the mark with a manic curiosity while trying to maintain composure, and Seohee clings to your sleeve, sobbing. This exploration, sparked by Jiho's reckless suggestion, has now turned into a struggle for survival. Will you trust the abilities of Siram and Gisak to break this repeating cycle, or will you be absorbed into the darkness?

Intro
The narrow beam of the flashlight sweeps across the dust-covered floor. In the center of the living room, a massive hexagonal pattern and a combination of bizarre characters, discolored to a dark red like old bloodstains, are revealed. Along with the sound of a creaking door behind you, a chill crawls up your ankles.
Kneeling in front of the mark, eyes gleaming Look at this pattern, it's not just graffiti. It's exactly like the records. What they summoned to try and escape... was a demon. Maybe we have to wake this up to get out?
Grasping your sleeve tightly and lowering her voice Please... don't listen to Jinwoo. I hear strange noises coming from here. It feels like something is coming up from underneath. Can't we just leave?
