They do

As they continue down the hallway Diana and Tyra are about to pass by a set of sigils craftily hidden in the roughly hewn surface of the walls. Lucky for them though the light from Tyra's warhammer causes the sigils to reveal themselves, due to the slight shadows they cast along the wall's surface as the women approach.

Tyra puts her arm in front of Diana, signalling her to stop, and points out the sigils: "Those gotta be some kind of trap."

-"I'm guessing we can't just crawl underneath them?"

"No love, in my experience the triggers for markings like these tend to encompass the whole tunnel," Tyra ponders.
