Cryosleeper
Cryosleeper Options is the third module of Ashes of The Domain, as well as the smallest of the three. It modifies and expands on vanilla Starsector's cryosleeper-related content, and its individual options and changes can be enabled or tweaked if the player has LunaLib installed. Despite what the mod description makes obvious, much of the content must be discovered by the player through exploration of the sector's furthest reaches.
Movable Cryosleeper
In vanilla Starsector, the cryosleeper cannot be moved by any means. The Cryosleeper Options module, however, allows the cryosleeper (and the Lost Ark) to be repaired and moved to any system the player wishes through a built-in Alcubierre drive. This is much, much longer than hyperspace travel, but is carried out autonomously by the cryosleeper.
The Lost Ark
The Lost Ark was intended to be one of many domain-era ships which would ferry immense quantities of human colonists, but was ultimately lost. It can be found in the remote areas of the Sector, similarly to Cryosleepers, but is far, far larger.
Compared to the Cryosleepers, the Ark presents an immensely larger defense fleet when encountered. Additionally, it allows the player to grow a colony's size to 8, as opposed to the 7 of a Cryosleeper. Reawakening the people onboard an Ark takes 400 days at a Cryorevival Facility.
It, too, can be repaired with a large quantity of transplutonics, after which the player can set a designated travel point for it. As it uses a similar Alcubierre drive as the Cryosleeper, it travels autonomously, but far slower than hyperspace travel.
Cryorevival Facility
The Cryorevival Facility allows the player to awaken people from Cryosleepers and Arks, and can be built on any colony where a Cryosleeper or Ark is present in the same system. It costs 300,000 credits to build, and has a base upkeep of 15,000 credits per month, scaling with population. Adds a population-scaling demand for organics.
Cryoharvesting Facility
The Cryoharvesting Facility, instead of granting bonuses to population, instead uses the people frozen in cryosleepers in an enormous organ harvesting operation that generates income and harvested organs over time. It costs 900,000 credits to construct and has a base upkeep of 10,500 credits per month, scaling with planet population count. Unlike the Cryorevival Facility, it adds a population-scaled demand for a supply of marines to function.
