You seem to be on the right track.
A hedgehog maiden tells you, "Luke died many seasons before I was born, but legend said that he passed through here on his way to Southsward to find Urgan Nagru [the Fox-Wolf?]."

An old hare says, "Yeah, I met Luke once. He said he was heading on to the island of Sampetra [the isle Ublaz controlled?]. Searching for some Veldask stoat or weasel, or some vermin of there sort."

Of course when you asked a mousewife she also had a different idea, "Was he the one that went off to Kotir after he heard the king green cat [Verdauga Green Eyes?] knew Vilu Daskar? I was only a dibbun when he passed through here."
