Austin Eyler was a human mercenary in the employ of the Orion Syndicate during the mid-to-late 24th century. He was born on Planet Q in the 2340s.
In 2351, Austin and his younger brother Alan were orphaned when the colony was destroyed by the Cardassians. Found and adopted by a Klingon House, the Eylers were raised on Sherman's Planet. In his teenage years, Austin rebelled against his Klingon upbringing. He eventually ran away, and disgraced his House by joining the Orion Syndicate. (Star Trek: Pendragon)
