The HHO Confederacy is a loose union compromised of many different fallen factions taken under the wing of the HHO government, and subsequently renamed. As such, the HHO have one of the most diverse populations for any single faction in the known universe. A unique characteristic of the HHO Confederacy is that all of their ships have designs based upon household objects (HHO stands for HouseHold Objects). No-one quite knows why.
The whole theme was inspired by Daniel Jassim's Nasal Avenger, which can be found here: http://www.mocpages.com/moc.php/3687
