Wyvern battle group was an Imperial battle group centered on the starship Wyvern that took part in the Second Battle of Fondor. After the surrender of the Fondorian forces, the Wyvern battle group almost followed the command of Chief of State Jacen Solo to renew hostilities against the Fondorian forces, only to be recalled back to their positions by Grand Admiral Gilad Pellaeon. It is likely that the battle group joined Darth Caedus after Pellaeon's death.
