Carcharan took the form of a giant bat. Like the other Vampires (who in Lord of the Rings are fallen angels, or alternatively fallen Maiar) he was a servant of Morgoth and dwelt in Mirkwood. Carcharan only appears in The Lord of the Rings Online.


Oddly, of the three named vampiric characters in The Lord of the Rings, both Carcharan and Gûlavhar, the Terror of Arnor persist long after Thuringwethil and her unnamed brood perished.
