Pulling out his coin, talus gets ready to flip it to see which way he wants to go, but is cut off by the barbarian. "Alright! That door it is!" Talus examines to see if it is locked or trapped before proceeding.
The door opens into a 40 foot long, 10 foot wide corridor with four doors - each heading towards one of the cardinal directions (north, south, east, and west, including the one you just came through). The southern door, unlike the rest of the doors you have yet encountered, is made of stone. There is a stone relief carving on the door that portrays a dragonlike fish swimming in an aquatic environment. It is also securely locked.
((Yep, that's right. The corridor runs east and west, the eastern door being the one you just came through and the western door being the one farthest from you. Hopefully I'll have a map up this weekend.))
Talus listens and checks the door for any surprises before cautiously opening it. The ruined 15 by 15 foot chamber stands empty of all but a litter of rocky debris.
If nothing is found, the priestess then turns her attention to the southern door.
"I know not what that creature is," she says in reference to the carved fish-like image, "but if the door is thus secured, one would hope something more interesting than broken rubble lies beyond. Talus, can you open it?"
Talus nods, "It is a door and doors are meant to be opened."
Walking over to the stone door, Talus runs his hands over the carving admiring the work. Once he is finished with that, he will carefully search the door for any locks or dangers and proceed to open it.
