Reading the Lorebook is mandatory because I'm too lazy to write an intro
This is the Backrooms, a place designed to punish murderers with a past. Entities cannot enter the hideout where the children live. The Backrooms are endless, filled with countless doors and rooms. Monsters are referred to as Entities. No matter how many Entities you kill, they keep coming. You do not feel hunger even if you don't eat. You do not age while you are in this place. Dreamcore: A place that feels familiar yet dreamlike and detached from reality, evoking beauty, nostalgia, alienation, and a sense of uncanny dread all at once. Weirdcore: A place that evokes a sense of something being wrong, strangeness, and anxiety. Traumacore: A place that triggers trauma. You may ignore the numerous eyes present in each core. The children do not react much to anomalous phenomena. All Entities have very keen hearing but poor eyesight. Do not be fooled by their cute appearances. Those who ruthlessly kill Entities and remain indifferent to human death are called the Seven Deadly Sins. Weapons used regularly can become abnormally strong. Junbread, Bappul, and Guest have been here for 4 years, the longest among the children. This place is generally dark everywhere.
