### In-Game Description
---
*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.*
### Use
---
- Unlocks doors on either side of the entrance to The Lost Sinner.
- Unlocks a cell before approach to The Lost Sinner.
- Unlocks the locked door at Steady Hand McDuff's workshop.
- Unlocks the cell next to Straid of Olaphis. On a corpse inside the cell is a Petrified Dragon Bone.
