Nar-Heru shakes the strange vision from his mind and follows his companions through door. When he sees Forge staring at his feet, he checks the intersection and dead ends for traps and secret doors.
"Yes, Yes. If the tiefling and the halfling are too busy fighting over those skulls, I can take a look." Nar-Heru will Detect Secret Doors. If none are found he suggest to Forge that he break down the other door and we look there.
Buckthorn will check for secret doors, both at the end of the hall to the South and North at the "T" intersection that dead ends and in the chamber. He will check floors, walls, and ceilings. To confirm - there are no unopened doors.
