Maybe a last sentence (Dariun's last sight), showing Socorro entering the place with the weapons (you don't even have to describe his death, just maybe have it like:
“I am sorry, Dariun.” He said, gazing out from his permanent squint. “I cannot trust you to take you any further. This is where your journey ends, my friend.”
The last thing Dariun saw, before the blood running into his eyes cut off all vision, was the old man, walking slowly into the gloom, unopposed. Then blackness took over, and Dariun saw no more.

Or whatever you want. I just think the ending is a little too open.
