Vanitri will examine the liquids and stuff, looking for anything potentialy magical. (He'll use his detect magic). Maybe there's a potion in here that will make him happy.
*There are several potions that detect as magic, but he has a bit of trouble identifying most of the auras. One of them is transmutation, but the rest he can't tell.*
Tenebrynn will wander about the room looking for something to amuse himself (search). If he finds nothing he'll poke his head out of the room wondering if the other two have found anything fun.
