Ren wouldn't have a problem in that department since he would turn into a bat and fly to the other side.

The dark elves knew the area well, and with their night vision, it was easy for them to navigate the difficult terrain. And within just one minute, the dark elves escaped through the mist while Ren was already waiting for them on the other side.
