(IC) The Stone Tooth
Taking the duegar at their word (however dim a prospect that was looking) that the undead lie to the "north east", Lyrian goes to the north doors on the east wall, and checks all for of them for traps (and locks), taking a few minutes with each one to be certain no one will get hurt going through them. If all is well, she will wait by the most northerly of the doors and wave the others forward to carry on.
OOC: Taking 20, or 2 minutes with each of the four doors, for a 35 Search check on each.
