Realizing the windiness of the twisty hallways, all alike, Guran resheaths his handaxe and, taking a torch out of his backpack, lights the torch. Guran holds the torch aloft in his left hand so he can still draw a weapon if there's an opportunity to use it.
Movement: Guran follows Colden as the fighter moves in the wake of Roscoe's furious assault, but leaves 5 feet of space between himself and Colden so others can use that space.
(Guran recognizes his own dismal performance so far in this combat, and wants to do whatever he can that might be more useful than an attack at range past allies who will provide cover for his targets. While Guran can see in the dark, he also recognizes that Colden and Roscoe cannot.)
