The main setting for Farscape: a living starship, a female of a species called Leviathan. She's called bio-mechanoid, meaning part machine and part living organic matter. While she travels faster than lightcc no explanation has been given for exactly how her drive works. (See Starburst.) Her size has not been defined, either, but she's cavernous with hundreds of rooms (called chambers) and dozens of decks. She's a living home in space, but it's a bit of a pity that she isn't also armed. (See also Pilot.)
