In the First Age, some groups of Drûghu had joined the fathers of men (or Edain) who had escaped from the Eastern Lands and had entered the Westlands. Some of these, the Halethrim, entered Beleriand in company of their Drû friends. These Drûghu were considered part of the House of Haleth, and came to be known as the Drúedain. Their late descendants near the borders of Rohan were called Woses, or "Wudu-Wasa", by the Rohirrim.
The language of the Drûgs is known as Drûghic.
