Inspiral

Inspiral is a lore book added with Lightfall and found in the Root of Nightmares raid. It catalogues depictions of the Darkness and its effects on different beings, and its ten entries include "The Habitable World", "A Sword, an Edge" and "Winnowing". Several entries reference the Black Garden.

Entries unlock through the raid itself: interacting with green bowls, completing some of its encounters, opening secret chests and opening the red border chest.
