Points of Interest
After dropping down into the prison, if one were to continue down the hallway past the entrance to the courtyard, there is a hidden room where the player can insert a charged Agonarch Rune. This will summon many waves of Taken enemies. Defeating them all will drop a chest that can be opened, which contains one of the Calcified Fragments.
Immediately to the left of this hole to the room containing this chest, the player will see a pile of rubble and old casks. Hidden behind said heap is yet another Calcified Fragment.
