Escape

The altar is destroyed, Harrow and Doctor dissolve, Thomas escapes the collapsing manor through crumbling stairs and corridors while the between-state unravels, Violet says goodbye, Thomas walks toward freedom.

Thomas and Harrow descend to Black Altar. Three trials: Perception (false exit illusion), Sacrifice (emotional armor surrender), and Altar Temptation (false Sarah). Thomas resists all three, Harrow sacrifices himself, Thomas strikes the altar.

Thomas discovers graveyard with 151 numbered graves. Finds his own carved initials proving he has looped before. Discovers Violet's grave and journal revealing Harrow's origin story. Harrow speaks, revealing this is Thomas's 4th iteration and providing intel on the Heart.

Thomas carries weight of mercy-killing David Chen as he explores first floor. Exits to garden, decides to stay and fight (motivated by David and Violet). Discovers Architect blue flowers, succumbs to pollen, wakes buried alive in coffin.

Navigate underground caves with sticky tar substances, follow slopes toward water, encounter snake-like creature in underground lake

Thomas descends the basement stairs methodically, using EMT training to assess threats. The construction shifts from Victorian to ancient rough-cut blocks - Harrow built on top of something older. Walls sweat a blood-like liquid. Mirrored footsteps track him two steps behind.

Thomas returns to the music room and meets Violet, who shares her story. When he sits at the piano, memories of Sarah singing on long shifts surface. He plays clumsy notes for Violet, giving her a moment of peace, then learns about the Heart that must be destroyed to free the trapped souls.

Discover secret room behind storage filled with wall of missing persons newspaper clippings, encounter radio with breathing sounds on other end, realize scale of Harrows victims

Thomas explores the manor's ground floor: the breathing front door that serves as a warning, the dining room with its rotting bait sandwich, a tar pool portal in the coat closet, a hidden study with decades of missing-person clippings and a radio receiving inhuman transmissions.
