|Cathedral Ward||Nightmare Frontier|
Former Lecture Building, probably a part of Byrgenwerth. Lecture halls are still full of former scholars sitting in their chairs. It's divided into Lecture Building and Lecture Building 2nd Floor, both with their own Lamps. A shortcut connecting both floors can be unlocked from the 2nd floor.
Entrance can be found in Cathedral Ward. Proceed from Grand Cathedral Lamp. At the very end of the road is a forgotten church with Lesser Amygdala guarding the entrance. Make sure you have a Tonsil Stone in your pocket and allow her to grab you.
The building is not physically accessible by any means as it's a part of the Nightmare.

- This location can be used to farm Blood Echoes. It can yield around 15000 echoes per run. The Moon rune can boost the farming productivity as well as the Bold Hunter's Mark.
- The Slime Scholar is weak to Fire and Bolt. Flamesprayer is an ideal choice to deal with them in large groups.
