We are the Imperial Enforcement Division
We were originally a group of mixed pilots of various backgrounds; traders, explorers and bounty hunters who got fed up with the scourge of pirates and murderers in the galaxy.
At the battle of Chi Lin we decided to band together in our trade ships and a few combat capable ships and, alone, not only repelled this attack, but managed to decimate the force and chase them out of the system (taking many a casualty in the attempt).
After the battle, after the smoke had settled, the community, themselves, asked the group to stick together and thus the IED was born.
Since this day we have vowed to keep Imperial assets and civilians safe but have, on many occasions, found ourselves behind "enemy lines" defending federation citizens from the same murderers who plague Imperial space.
