The main area of the Bloodhouse.

The Bloodhouse is an important location in the Scarlet Lodge headquarters beneath the Eden Theatre. According to Sabinian, two Rubies are required to enter the Bloodhouse. Dr. Austerlitz rewards notable members of the Scarlet Lodge with these Rubies. In the Bloodhouse, the Scarlets can indulge in their most depraved sexual urges.

Captured Seeing are brought to a special area in the Bloodhouse, where they are locked in cells adjacent to pleasure rooms. When they are forced to transfer to Lusst'ghaa, they are sent to the pleasure rooms to receive the sexual stimulation required for the trip.

The three hand keys required to open the Hall of Whispers are always stored in the Bloodhouse when not in use, though they are not stored near one another.
