The Havse Sanatorium - AI-generated fantasy Building

The Havse Sanatorium

A sprawling, two-story structure built of soot-stained brick and rotting timber that looms over the outskirts of the city. The windows are heavily barred with rusted iron, and the entire structure leans precariously as if sinking into the marshy earth. Inside, the transition from hospital to prison is complete: the air is thick with the scent of caustic lye, unwashed bodies, and a sweet, sickly aroma of alchemical rot.

The Havse Sanatorium
Mental Asylum and InfirmaryHaunted and decaying. The building exists in a state of entropy where walls peel like dead skin and the spirits of the tormented dead are physically tethered to the rooms where they expired.Large. Two main floors with a central observation spire and a restricted basement laboratory.

The Havse Sanatorium

The air is heavy and stagnant, vibrating with an unsettling psychic resonance. Distant, rhythmic thumping sounds like a heartbeat through the floorboards, while the frantic whispers of the inmates create a constant white noise of despair.

History

Originally established as a sanctuary for the city's destitute and mentally broken, the sanatorium fell into darkness under the leadership of Nurse Brosla. Over the last decade, it transitioned from a place of recovery to a site of illegal experimentation. A chemical spill in the basement labs three years ago killed several staff members, and their spirits have since merged with the building's decaying architecture.

Alchemical Hazards

The Therapy Wing is perpetually filled with a faint green haze. Any creature that spends more than 10 minutes in this area must succeed on a DC 13 Constitution saving throw or become Poisoned for one hour. While poisoned this way, the creature suffers from vivid hallucinations, granting disadvantage on Wisdom (Perception) checks.

Containment Protocols

The Patient Quarters are guarded by reinforced doors (AC 19, 25 HP). Many cells are inhabited by Berserkers who have been driven to a permanent frenzy by Brosla's treatments. They will attack any creature that is not wearing a nurse's uniform on sight.

The Living Haunt

In the Restricted Area, the walls function as a Lair Action. On initiative count 20, the building may attempt to Grapple a creature standing within 5 feet of a wall (Escape DC 12) as the wooden slats and mortar physically reach out to grab them.
