Splithoof Heights is the Galak centaur village, on the large shelf to the north of the Shimmering Deep in Thousand Needles. It's here that the Galak retreated to from Splithoof Hold, Splithoof Crag, and Camp E'thok to survive the flooding caused by the Cataclysm.
The tribe starts out neutral, but along the quest chain players get the centaur mad and they become hostile and remain that way.
Patch 4.0.3a (2010-11-23): Area added.
