Earena

Earena is an alien fox like species called the Gentra. The Gentra were humanities' first contact with an alien species. The Gentra are embroiled in an interstellar war with another alien species called the Ambralins. Ambralins are an aggressive neighbor of the Gentra and have been colonizing planets in Gentra controlled space for generations. This was the catalyst for war. Due to the extremely advanced technology level of both species, ground warfare has become nearly nonexistent. To the point where either side dont bother to land troops on a planet, they just control the space around it. Humans entered the equation for access to better tech and have proven to be a valuable tool in the war if the Gentra can hold or contest high orbit. Humans have become interplanetary marines for the Gentra.
