The Blue men are blue-skinned men on the continent across the Eastern seas. They are from the Northern portion of the continent, and are naturally borne with blue skin. They are considered untrustworthy and ambitious by the Wolf Raiders.
Notable 'blue men' include D'Rance, who was a part of the Wolf Raider force that invaded Legar during the events of the Crystal Dragon. D'Rance was eventually killed by his own ambition when he tried to betray the Wolf Raiders using a magical force he did not completely understand.
