Nathwyr is a Whinno-hir who was the mount of Narth, Lord Harth of East Kenshold. He refused to allow Narth's son to ride him; when the young Lord Harth's yondri, including Marc, insisted that a Whinno-hir cannot be ridden without its full consent, he ordered the yondri to leave.
- ↑ Dark of the Moon, "Chapter 3: Old Friends, Old Enemies" — " 'That's probably young Lord Harth, trying to ride Nathwyr again,' said Marc bleakly. 'Nath was old Narth's mount, a full-blooded Whinno-hir. We older yondri tried to tell the boy that no Whinno-hir can be ridden without its full consent, but he wouldn't listen. We insisted, and he ordered us to leave.' "
