The druid looks around the empty room, slightly disappointed by the utter lack of anything curious, at least at the first glance.
"No, there is nothing besides an empty room. Not unlike the one below," he calls out to his companions, while raising his hand with the flame higher, to banish the shadows in case there is anything else hiding from view.
"There are more stairs, however, if we want to explore further. I think it's best if we continue together, if Lex is done with his experiments."
Despite his cautious words, the druid still walks further into the room. He doesn't ascend to the next floor, but he wanders around this one, peeking into the corners and checking out the column for any detailing - in case decorative engravings or even the shape of its foundation can tell him anything about the tower and its origin.
OOC:
No idea which would be the most appropriate here, but my History and Investigation are +2, and Insight and Perception are +5.
