Ah. Reading back, it seems I said that he will tell the magi what he saw happen that night, but didn't actually. So, either while they're preparing for the trip or when they arrive at the Temple (which is about a five or six hour walk):
[color=green]"The magus Fieltarn asked us to accompany him as he looked into reports of wolf attacks on the residents here. We arrived at the cottage of Vincent, and I could hear wolves gathering in the distance. The magus said that there were other wolves closer. Spirit wolves, that were hunting for a boar that Fieltarn had already killed. Fieltarn said that he would try to get the wolves to accept his sacrifice in exchange for our safety. The wolves appeared around Helmut, who barely made it into the cottage. I was able to kill one of the wolves that was attacking him.
"Fieltarn threw some tusks in front of one of the wolves, who..consumed them, somehow. The magus then told us that the situation had been resolved, asked us to make sure that Helmut and Vincent's family was safe, and said that he would follow the wolves, warning us not to loose any more arrows. He then told me, specifically, not to leave the cottage until dawn.
"He had us leave a bundle of his clothes by...that post there," he continues, gesturing to the post that Fieltarn had specified.
[color=green]"I went into the cottage with the others, and sat by the window to watch. After a long while, Fieltarn turned into a wolf, and ran with the others into the ruins. We waited the better part of the next day, but he did not return, so we returned to Mons Electi. I have kept watch for him for several days before I decided that you should know."
((edit - replaced "Fieltarn threw some bone in front of one of the wolves, who ate them" with something closer to what Wilhelm saw, per PM from JL))
