Fight against the priest, or maybe not.

Endl managed to run and hide in the other run, so he could see the priest passing in the other corridor without even looking to the side, if he had a better perception or some search magic, surely he would have found Endl, so he was a little worried, but after the priest passed, he calmed down.

'Now is my time.' Endl I take advantage that the priest had passed, and let him get away a lot, and soon after that he followed the same path that the priest had come from, this can be a way to find the place to get out of here.

The only problem is that this place is so big that it's difficult to know where he went, and where it's a new place, it's very easy to get lost in that place, but probably the priest can walk here normally since he must have stayed here for a long time.
