Boro is a young volus colony world, settled in defiance of a threat by Terminus pirate groups. The pirates, who can't use the world themselves, have "suggested" that the volus "hire" them to protect the colony. The volus responded by requesting military protection from their turian allies.
Although uncomfortably hot by volus standards, Boro has the rare combination of high pressure and ammonia ecology volus require. Development of the colony is proceeding rapidly.
