Arcturus

The Arcturan system was a star system located along the Federation-Klingon border. The system was largely ignored by both powers, and in the 23rd century became a haven for thieves, smugglers and pirates.

In 2264, the Klingon renegade Koronin obtained a Klingon Bird-of-Prey after beating its captain in a game. She renamed the ship Quundar, and set off for the Federation Phalanx.
