Ruul Snowhoof[41, 34] is a level 26 quest giver located deep in Thistlefur Hold in the contested territory of Ashenvale. A tauren druid, he was captured by the corrupted Thistlefur furbolgs while in bear form. They believe him to be a bear and are, for some reason, starving him to death.
Ruul has apparently not changed form in front of the Thistlefur to prove to them he is a tauren. This could be because he believes he would be treated worse if they knew, or because the cage is too low to the ground to accommodate his humanoid form.
