The Immolator was built using the original designs of the Ehrgeiz. Of course, changes were made. It's frontal armor was severely reinforced, as to make the ship a viable option for full on assault. While the Core rarely meets their enemy head on, sometimes, this tactic is employed, depending on the situation at hand.
The rest of the Mako itself is standard issue. Being one of the more frequently used warship, it was meant to be relatively cheaper to fix and it's more advanced counterparts. Currently on station in Omega-55, tasked with protecting Dagger station and acting as a massive vibe check for all who dare attack both the station and core patrols in the Omegas.
The Ehrgeiz was transferred to the Bretonia Armed Forces, in exchange for the Caesar.
