After the assassination of Director Apollo, Shane Nova was appointed Director of the Federation. As an ape known to be a master of manipulation, some suspect Nova was involved in Apollo's murder. Nova skillfully used this assassination as political leverage to invoke fear and impose his administration's agenda throughout the galaxy.
As the acting government with virtually unlimited power and resources, the Federation ordered robotic peace keepers be sent to each planet to ensure order was maintained. This violation of basic monkey rights led to the uprising of the Resistance and sparked the beginning of the Galaxy War.
"It's not what you speak that influences, rather how you speak it." - Director Nova
