As the adventurers rested, a half-elf wearing plate armor bearing the symbol of Avandra came down the stairs and caught up with them. He introduced himself as Ooga de Booga and explained that he is looking for “Catdog”. He agreed to fight alongside the heroes until he found Catdog. After introductions were made, Gok led the way down the next set of stairs and into the next chamber.
The room proves to be some sort of chapel, with murals of deep sea creatures and fanged monsters covering the walls, and two pairs of serpentine statues, one flanking a lower worship area, and one set flanking a narrow stair leading to a basalt altar itself decorated with a rising eel carved from the same piece of stone as the altar. As the heroes look around the room they are greeted by the voice of an old man, urging them to “cease this unnecessary violence. Lay down your weapons and pledge yourselves to the Lord of the Depths, and you will be forgiven your bloodshed, welcomed into our family, and generously rewarded for your commitment.”
Boraheen was repulsed. Usually calm and polite, if not always tactful, he made no effort to hide his disgust at the offer to join the cult of Dagon. “No damn way any of us join you. For the atrocities committed upon outsiders, I will show you Justice.” On hearing the dragonborn’s refusal, the old man made a gesture and four fish-men appeared from behind the four statues and combat was joined instead of a cult.
The fight was not easy. The old man turned out to be a spell-caster, and multiple times he would conjure large swirls of wind and rain, forcing the heroes to brace themselves and stop their advance toward the apparent cult leader. Nonetheless, not long after Gok closed the distance between himself and the “old man who smell like fish too much” the man lay dead across the black altar. G’Narsh decided to celebrate by using his hammers to destroy the eel that rose from the altar by chips and flakes.
