On live, I was leveling and found this rare (through Wowhead comments): https://www.wowhead.com/npc=186355/tripletath-the-lost
Coords: 57,60 in a cave at ground level
Tripletath doesn't show up on the list of rares for Forbidden Reach in the addon currently
Drops an item that gives a slow fall buff: https://www.wowhead.com/item=197727/mystical-water-vial
Possibly tameable as a rare beast (Hydra)
