Rimefang is a frost wyrm of the Frostbrood. Rimefang was originally the frost wyrm mount of Scourgelord Tyrannus the dreadful master of the Pit of Saron, who was killed by the champions of Jaina Proudmoore and Sylvanas Windrunner. Rimefang fled the scene and now waits as a guardian ready to kill the Ashen Verdict's heroes invading the Frostwing Halls.
