The Sovereign was a class of warship nearly as long as the Eclipse Class and even wider than the Executor Class . While Dark Horse comics created the ship, and Michael Allen Horne wrote up the ships abilities, I got to name her and her sister ships, the Autarch, the Despot, and the Heresiarch .
As of Darth Vader Comic #13, the name has given to Grand Moff Tarkin’s Flagship.
While the class of warship is not the same as the original 1991 behemoth, I’m still happy as a well fed Hutt! Grand Moff Tarkin is my favorite Star Wars character.
I had always pushed for the ISD Tyrant which I had also named (for Topps cards) to be his flagship but that never made it into Canon. That ship is still part of Death Squadron in current Canon.
