Interested? Sure.

Just know that it would be in line with Xir'ain's character to attempt to kill it upon their first meeting. As far as finding him, since Xir'ain's tunnels spread in every directions just below the ground, and since Balon would be really heavy, what if his foot broke through the ground and fell into one of the watery tunnels? The eels would totally frenzy and try to eat him, but I'd hope he wouldn't let them do that. Xir'ain is 150 miles away from his dungeon's heart at the moment, closer to Ensis'Lucas actually, so he might be busy dealing with things for a little while before he can direct all his attention towards a certain pestilent giant.

Right now I'll see if I can throw together a post that gets Xir'ain back to the heart at least.
