The Old Monk Archstone is a location in Demon's Souls.
- Archstone of the Demon Old Monk
- His revenge complete, the old man withered, possessed by golden robes of insanity. Too weak to be a demon's vessel, his soul was eaten.
This Archstone serves no real purpose other than an easy way to get back to The Nexus after killing the Old Monk. It is accessed through the Archstone of the Tower Queen.
