The investigation begins in Oscar's room, where a diary documents his recent descent into obsession with occult practice and ritual. The details in the diary are specific. Townspeople have been talking about an abandoned mansion at the edge of the forest where darker rituals are reportedly conducted. Following the evidence to the mansion means entering a building that was clearly designed to resist being understood — riddles embedded in every corridor, eerie visions that appear without warning, artifacts whose origins suggest connections to active demonic agreements. The truth of what Oscar was involved in is in here somewhere, buried under cryptic documentation of what someone was working toward.
