Shrike

Leader of the Passage cell of House Tarkanan, Shrike is a cunning and pragmatic career criminal and smuggler. Her chosen criminal organization, House Tarkanan, is organized as a parody of the Dragonmarked Houses, and gladly welcomes aberrant marked members to join and oppose the Houses from the shadows... especially when it makes money.
Meeting Diiroehn through mutual contacts, she aided him in making "contact" with his aberrant mark, or the being behind it. Later when the Houses threatened Beacon, Diiroehn assisted with a smuggling operation, and won her assistance with espionage and sabotage of the House's fleets.
