Not thinking to have brought a light source, Reiko falls back to allow Aroden to take the lead.

Aroden in the lead, currently with a soft white glow from his blade ... is stymied. Normally, the glow is as bright as a torch, but his sword's light only chews into 5' of the darkness before it is stopped cold.

For her part, Bríg realizes her elven vision avails her none. She only sees as far as the 5' of light cast from the sword ... and no more.

Only Mordren and Grathar seem to be without penalty.
