- Ancient ancestors of the Rockmen.
Descended from a splinter group of Rockmen who rejected their species' violent ways long ago, the Crystalmen are almost completely unknown in the galaxy, having hidden from all other sentient life. They can be encountered as starting crew on the Crystal Cruisers, in Tektite (the 3rd layout of the rock ship), in the Dense Asteroid Field Distress Call event, or within the crystal sector itself (they are at shops to recruit/found as prisoners/etc). Acquiring a Crystal crew member from the aforementioned event allows the Crystal Cruiser quest.

Lockdown: Active ability that coats the room they're in with crystals, preventing anyone from entering or leaving and making the room itself invincible to damage. The crystals wear off over time, or when attacked. This ability requires time to recharge after being used.
Potential strategies to use Lockdown could be during a boarding attack by locking down your most precious system room or during boarding enemy ships by locking down a room so your crew can destroy the system in it uninterrupted. One particular example would be locking down the Medbay on an enemy ship, so it can be destroyed before any crew members are able to reach it, making it much easier to board and kill the crew of a ship that has one. With multiple crystal crew, or few enemy crew, it is possible to trap injured enemies so that they can't reach the medbay anyway.
The crystal race was created for a donor that contributed 2,000 USD to FTL's Kickstarter campaign.
