They follow the hallway, which widens ahead into a chamber

Tyra quickly casts light on herself, revealing a little ways ahead the hallway broadening, entering a square chamber that looks to be about thirty to fourty feet across. At the end of the hall, at the chamber’s threshold, stand two plynths similar to the ones encountered at the beginning of the dungeon, except on both of them there appears to be set a metallic-looking orb, glowing ever so faintly. As Tyra gets a little closer, she sees that the bottom of each orb has melted, and a puddle of metal formed around their base, cooled off and solid. Further ahead in the distance, at the back of the room, they see where their weapons have been dropped.

”Well these plynths sure looks suspicious,” Tyra says over her shoulder at Diana, who walks up to inspect the plinths as well.
