Xandar. Nova Corps. At first, the Nova Corps consisted of Xandar's space militia and exploration agencies. Later, the Corps developed into a force of five hundred soldiers ranging from guards to Centurions, including the leader of the Centurions—the Nova Prime—and a regiment of soldiers. After a long period of reform, the Nova Corps expanded its protection to encompass the entire Andromeda Galaxy. They were also known as Xandar's interstellar military corps, and Queen Adora held supreme command over the Corps.
