I imagined this armour set while working on the map completion of Ascalonian areas, considering Ebonhawke's colours as well as looking for a fierce look that said "I'm the one you should fear."
A lot of homage was paid to the Ebon Falcons and Keiran Thackeray as well as my favourite character Dian Fermati. ("99 bottles of beer on the wall...")
Thus in my eyes I consider this uniform/armour set a modernized form of the Ebon Falcon's gear combined with Ebon Vanguard colours to symbolize the elite of the pack.
