Burko

Burko is a draenei master first aid trainer and vendor located at the Temple of Telhamat in the Hellfire Peninsula. In addition to the training tome, he sells manuals for Netherweave Bandages and Heavy Netherweave Bandages.

From the entrance of the temple, go forward up two flights of stairs, then take the path that goes west/left. Burko will be standing inside a small building.

Speculation
The similarities in physical features and clothing suggest that Kuma, the hippogryph master, might be a twin or a brother of Burko.
