This is the Pantheon of Hallownest extended. It included EVERY. SINGLE. BOSS, excluding Zote the Noob. Up arrow for the previous backdrop, and down arrow for the next backdrop.
I was thinking about adding the Pale Court Bosses as well, but I couldn't find an image for each of the bosses (Ze'Mer, Dryya, Isma, Hegemol, Ogrim and Isma) that didn't have dream particles in the background.
