The knight takes a bold military attention and announces: "This area is the B15F prison outpost of Hellfire, under the watch of Hell Lieutenant ser Ysmus. Hell Private Jhakarias, order of the Lantern, presenting." Emboldened by his military pride, he continues: "Authorization to proceed must be earned from a Hellknight of the rank Corporal or higher."
"Should you truly wish to enter through that door, you should speak with Corporal Matt. He's resting in B16F, not that far from here. Just go straight there," pointing towards the tunnel next to you, "take a turn right, head down, and keep going forward."
