The Ascendant Spear was a Terminus-class destroyer that had been modified into a long-range battle cruiser with a Class 0.5 hyperdrive. This made it incredibly fast in hyperspace compared to the other capital ships of its time. Because of this speed it was considered a Superweapon by the Sith Empire.
Like many capital ships throughout history, the Ascendant Spear had a dagger-like hull shape, as with many cruisers, destroyers, battleships, etc. affiliated with the Sith. It had two command bridges on its dorsal surface towards the back of the ship set at slight angles. The Ascendant Spear utilized a megalaser, which was a concentrated laser weapon that could fire multiple times and destroy a large ship in a single blast.
The reason the Ascendant Spear was classified as a superweapon was because of its unique capabilities. Darth Mekhis created the ship to be the perfect union of man and machine. Through bionic implants, the former apprentice of Darth Malgus, Darth Karrid, communed with and controlled the ship directly. However, this required intense concentration and a steady stream of power flowing from her apprentices to bolster her own. Because of this, Darth Karrid would only assume command of the ship during combat.
The Ascendant Spear was one of the most devastating Sith weapons of its period. It regularly wiped out entire Republic fleets, as well as Sith ships who attempted to flee from the conflict.
Using the Sun Razer, the Sith Empire was able to complete its creation in years instead of decades. All the projects fueled by the Sun Razer were overseen by Darth Mekhis and discovered by Theron Shan and Jedi Master Ngani Zho upon their infiltration and capture in the Vesla system.
In 3640 BBY, Theron Shan and Jedi Master Gnost-Dural (Karrid's former master) captured one of the few surviving Black ciphers, and used it to predict the Ascendant Spear's location. They snuck aboard, and Theron sliced into the network and covertly sabotaged the ship while Gnost-Dural allowed himself to be captured and interrogated by Darth Karrid, in order to lure her into an ambush.
