This episode is just full of lore!! Senshi being the caretaker of the third level, how golems work, people in the dungeon, orcs, what their history is with other races. The story that the chief tells Laios about the master of the dungeon, and that if anyone we're to defeat that mage, they'd be rewarded with all that the underground castle has to offer.
Marcilles argument with the chief is hilarious, and the gang realizing Senshi surrendered to the orcs just so he could make bread, had me dying.
