Kylaena was a Twi'lek assassin of the female persuasion. Her assassination of Ead Vionor, a key stakeholder in the Bunkurd Corporation, resulted in her landing on the Bounty Hunters' Guild's list of top ten most sought-after criminals in 1 ABY. It was also believed that she had carried out fourteen additional assassinations in the six years leading up to that event. Ultimately, an unidentified bounty hunter located and eliminated her.
In the video game Star Wars Galaxies, a massively multiplayer online roleplaying game that LucasArts published and Sony Online Entertainment developed, Kylaena was a non-player character. This game was released in 2003 and shut down on December 15, 2011. With the launch of "Game Update 3" on April 29, 2008, Kylaena was incorporated into the game as a component of the "Dangerous Fugitives" collection.
The Star Wars Galaxies designer Janessa Johansson was known by the nickname Kylaena.
