The UGI Invictus which means Unconquered was added to the roster next to the Judgment when it was built with new UGI Technologies that allowed them to replicate Derexium without having to have some stored up.
Built as any other Extant this ship had its armor "Replicated" as well as much of the ship was. THe most important feature added to the ship as well as as all UGI vessels after and even had the older ones installed was a Temporal Lock Device. This prevented the ship from being dragged into an Temporal field without its permission as well as Temporal weapons rendered ineffective,
Built for war, and devastation is exactly what the Invictus brought the UGI when during the Nephalim War the Invictus for once lead the charge the first time the Judgment wasn't the face of the war. Due to Erex growing tired of War another Taiidan one more dangerous but even far more traditional commanded this vessel.
