The Dreaded Playtest
Having secured passage from Solandir to Valindor, you set out across the Sunrise Sea. Three days out, a deeply unnatural storm shattered the ship, leaving you adrift in a stormwracked sea. Then they came for you. Creatures with the faces of men, and the bodies of some tentacled horror. They dragged you down beneath the waves until you blacked out.
When you awoke, you were in a stone room, surrounded by the dead drowned bodies of the crew. The walls were covered with disturbing bas-relief images of tentacled horrors embracing humanoids. Above the immense doors runes ticked through a countdown. Through a circular glass in the center of each you beheld another room with disturbing iconography, but within it were two cart sized heavily armored lizards with club like tails.
