Some characters look good in a suit; some characters _are_ just suits.
General Joel Fabin was a werewolf who was a leading officer in the Tech Infantry. He joined with Sarah Dunmeyer and was there for the initial failed coup. Although he continued to lead a legion for the TI faction in the 3rd Civil War, he grew increasingly dissatisfied with Dunmeyer's handling of the war. After the disaster of the Battle of Avalon, he overthrew her and placed himself as the leader of the TI faction. Unfortunately for him, the damage to the rebel cause had already been done, and the faction's forces were finally defeated near the end of the war. Fabin was eventually forced to abandon the rebel capital of Wilke's Star and is believed to have died after making a last stand in the Van Diemen system.
Behind the Scenes
Joel Fabin is a friend of Frank D'Antuono who once joked that "I'll never join the military with any rank less than Major-General." So he was entered into Season 4.3 as a major general. He was used in Alistar Dimiye's storyline as his connection to the political backstory.
