Key to the cells of the Lost Bastille.
Long ago, a bastille lord, driven to desperation
by the rapid spread of curse across the land,
began to see each subject as a carrier of the
blight, and locked them away in droves.
This entire bastille was turned into a prison,
and left abandoned to rot with its prisoners.
- Located on corpse near the Upper Ramparts Bonfire in Belfry Luna, after the Belfry Gargoyles boss fight.
