The Prosslee were the former oppressors of the Forshul, a species indigenous to the neighboring Yminis sector. During the Caamas Document crisis, the Prosslee senator took a pro-Bothan stance in opposition to the Forshul. At least one Prosslee escort frigate participated in the Second Battle of Bothawui, fighting first on behalf of the Bothans, and then as part of the united New Republic fleet.
