[that was actually interesting to witness, but the fireballs do help to light up the corridor, if briefly. there was more water, soaked walls, and Kid swore he saw something slithering through the shadows, but it had disappeared.

but he also saw some broken table wood just a few feet in front of them by the wall before it became completely dark again.]

Did you see that broken table? Think you could try aiming your spell at it and see if we can ignite it? The corridor is damp and I didn't see anything hanging along the walls, so it's unlikely that a fire would spread.
