The Incalculable II was the first Nymean Star Destroyer produced at the Areltsi Shipyards.
After the destruction of his first flagship, the Incalculable, Trivas made this ship his new flagship. So far, it has served in several conflicts, none where it received much damage. In the Breaking of the Corellian Blockade, it saw its first true action where it helped destroy several enemy frigates and corvettes. Since then, it fought in the Battle of Areltsi and several smaller skirmishes during the Galaxial War. The Incalculable II was with Trivas at both the First Battle of Bothawui and the second battle in that system. After that, it accompanied Trivas to the signing of the Treaty of Ruusan.
After the War ended, the ship continued to serve Trivas as his flagship and was based at Ni'novia. On a trip between Ni'novia and Areltsi, the ship was mysteriously abandoned and all the crew were killed in confrontations with Siron's Organization. Trivas and his apprentice, Dradin Kitsch were killed as result of that even though Dradin was able to escape into a clone. Inquisitor Reaves managed to track down the ship after someone reported it abandoned.
After investigations were complete, the ship was turned back over to the Nymean Ascendancy along with dozens of other Nymean ships that were loaned to the Ni'novian Empire during the War. It then became the flagship of the First Nymean Fleet under the admiralty of Admiral Repness. After Repness retired, the ship was turned over to Admiral Erstis.
