Pressing on.
The rhodin's wrists are left tied together, but he is able to move on his own. (Not sure if y'all were planning on gagging him or anything else.) He puts up no fight and is cooperative in moving through the caves.
The passage is mostly natural, with only isolated areas cut out or filled in to make walking more comfortable. The giants have the most trouble, frequenly having to hunch over.
For over an hour, the group treads slowly and methodically. There have been a few wider chambers and side passes, but the tracks of the rhodin are easy to follow and continue down the main path.
Aurial is the first to hear a sound up ahead. When the group stops moving, everyone can hear faint, high-pitched chirping. It sounds like a colony of bats, which would not be out of place in a cave. The rhodin seems just as curious as everyone else.
