Reaver

Reavers are those Luxons who mine the jade from the Jade Sea. It is a term adopted from their nautical heritage.

Trivia

 * In the TV Show "Firefly" and the following movie "Serenity" Reavers were Space Pioneers who "saw the 'Edge of the Universe' and went mad" (although the real reason is much more sinister).  This description of a reaver coincides with the Outcasts in-game though.
