Radbug by Jon Foster

Radbug was an Orc under the command of Shagrat at the Tower of Cirith Ungol. During the Battle of Cirith Ungol Radbug had his eyes squeezed out by Shagrat, killing him. It is believed that Radbug had refused to obey him.[1] Shagrat threatened the Orc Snaga with a similar fate if he didn't follow his orders.[2]
