Achenar drew the irritation of the Federation at the start of 2323, when reports reached Earth that the colonists had wiped out a sentient race on the planet. This, coupled with the refusal of Achenar to become a member, caused the Federation to send a battle group to take control of the system by force.

The fleet eventually arrived in the Achenar system at the start of 2324. Gathered intelligence meant the Imperial forces ambushed the Federal forces as they jumped into the system. What they hadn't predicted was the enemy to use their pack hunting formation against them. Tourist Beacon 0129
