Deneb, lying on the border between Itani and Serco space, is a common location for combat between the warring peoples of the Itani and the Serco. Currently, this combat is embodied in the Border Patrol mission and the recurring Border Skirmishes.
Border Skirmish
This battle takes place every four hours in Deneb B-12, the wormhole between Serco and Itani space. It involves both capital ships and fighters, and will continue until one side or another suffers enough casualties to withdraw from the battle.
