From Creatures Wiki
The Shee were a race unique in their mindset, most likely having invented the steam engine as an offshoot of an attempt to design a better way of brewing tea before they invented the wheel. Shee technology was often biologically based, as seen in creations such as the Shee Ark from Creatures 3. Their genetics are diploid, but the genetics of their creations are haploid.
Did you know? In Celtic mythology, The Shee, or more properly, Sidhe (Siðe), were faerie folk. They must have seemed all-powerful to the ordinary humans, as are the Shee to the other Creatures.
Creatures 3's The Lone Shee
The most renowned Shee to date is the Lone Shee, who reportedly left behind a series of notes and journals that recorded his adventures concerning the Warp (these events tie closely to the Docking Station storyline).
