Razzashi tribe

Nothing is really known about the Razzashi tribe. It was formerly mentioned by the Razzashi Coins, found in Zul'Gurub at the first engagement of the Horde and Alliance. The other coins refer to tribes, but no other mention of the Razzashi tribe can be found.

Razzashi is a species of raptor  and a label found on types of serpent.

Speculation
The animal species may have been named after the tribe like other beasts the tribes bred.
