The Magellanic Alliance was an alliance of 20 planets in the Magellanic Cloud founded by Isabella Ortiz. The Alliance held for a period of time, but was eventually conquered by the Kalderans. According to Dylan Hunt, the Magellanic Alliance was the only stable government located in its area of the universe. The Magellanic Alliance was apparently protected by a "Self Defense Force." The Alliance was led by a president.
