The "Enduring Conviction", once commanded by Let 'Volir, was one of the largest ships in the Banished Fleet and fought in many campaigns during the Human Covenant War and Post War conflicts, the most notable being its swan song, the Second Battle of Installation of 00. While it was not used for many engagements in the battle, the fact that it stayed above the Ark, dropping troops and resources down to the surface was what helped the Banished keep their foothold until the SPARTAN-II Commando Jerome-092 and UNSC AI Isabel managed to trick local Sentinels into destroying the ship, causing it to crash down on the surface of the Ark, where it now rests.
Enduring Conviction is a completely aesthetic map, designed to replicate the section of the ship seen in the iconic cutscene from Halo Wars 2 where the ship is destroyed. I decided to try and replicate this in Halo 5's Forge. Additional corridors were added so that the map was not just a floating platform leading to a teleporter and the room itself
