|"Calder Cob" is a concept which has only appeared in an adaptation of the works of J.R.R. Tolkien.|
Calder Cob is a character created specifically for The Lord of the Rings Online.
Calder was a citizen of Archet who turned traitor for the Blackwolds by supplying them information on the town's defenses. His treachery was uncovered by Jon Brackenbrook, the son of the Captain of Archet. Captain Brackenbrook was unconvinced of Calder's betrayal because it was Calder who had previously imprisoned the former leader of the Blackwolds, Otto. Captain Brackenbrook was eventually convinced by Dirk Mudbrick, another soldier in Archet. 
Calder was imprisoned in Archet but escaped along with Otto in the Assault of Archet after killing his jailer Ned Pruner. Calder was killed at some point during the Assault .
