Sanctuary Door

The Sanctuary Doors are a series of massive warp gates constructed by the Ommeret to aid their escape from the last Naiad migration. While warpgates are, by themselves, considered a dead-end form of FTL travel, these ones worked in conjunction with the shock cores on the ships, allowing the gate to propel them far further through shockspace than their own drives could take them, and still allowing them to exit shockspace safely. One of these, in the Axh Lonac (Final Line) system, was the subject of a continued assault by the Naiad swarm, and was where the Ommeret Empire's naval forces made their last stand to keep the gate open for as long as possible. Several others were built in secret, allowing them to operate relatively safely without being noticed by the swarm. It is implied that the ring in Node 01 is one of these gates.
