Designed by the infamous Dr. Kesten as a means to let dead warriors continue to serve, the Isenguard class series was a short-lived concept consisting of only two individuals. Each ship is grown around an egg using Third technology consisting of living flesh and crystalline matter to form it's hull, unlike anything built by Human hands.
When originally constructed, the Tersi was commissioned as the Darkso, however the ship's core consciousness was later replaced with her mate. At the time of construction, the Isenguard class was capable of obliterating entire fleets of human ships, and while those capabilities have been reduced due to human technology advancement, she is still more potent than any other single ship in the human fleets. She has recently undergone a massive retrofit to reconfigure her design to suit modern warfare technology and tactics.
