Lore is the written and spoken background the dungeons hand out as you explore. Centerpieces are one of its sources, alongside weapons, rings and gold.
Lore slabs and orbs
Secret rooms contain lore slabs and lore orbs. The orbs give a short vision of a boss, and the boss pages on this wiki quote them directly — for example the Slime King's orb and the Hunter's.
An orb that shows nothing is itself information: community sources report that "You gaze into the orb and see nothing" means The Killer has replaced that floor's usual boss, which only happens once The Hunter has been defeated.
Other sources of lore
The Bestiary entries quoted across the enemy pages, the note letters, and the dialogue of the NPCs are the other main places the story is told.
Compiled from what this wiki already says on Rooms, Centerpieces, Notes, NPC's. No new facts were added.
