Invincible-1 (Invincible-class Prototype)

The Invincible-1, otherwise known as "Old Reliable" was a prototype Star Dreadnought conceived in 4 ABY after the Battle of Endor.

History
The prototype was hidden in the Maw Nebula after the fragmentation of the Galactic Empire until it was moved to the Outer Rim. It was sent to Eraidu where it was used as a training ship for cadets of the Eraidu Naval Academy. It was later inspected and evaluated by Grand Fleet Admiral Haus. He determined that it could prove useful but ruled it out in favor of the Dominion-class Star Dreadnought which was considered a better alternative.

Legacy
The prototype Invincible-class Star Dreadnought remained a training ship throughout the existence of the Haus Dominion and was still active as a training ship in 65 ABY when Dan Haus returned from the dead to lead the Haus Dominion. The prototype would be given the official nickname "Old Reliable" by Dan Haus and would be the scene of many famous events and ceremonies. Though the ship never saw combat, it was popular nonetheless with navy officials and diplomats of the Haus Dominion.
