History
Primor is a grey-class Sionnu, the slave class. He earned his freedom by murdering all of those that claimed they were his masters. He hated the idea of being someone else's property.[1]
He unleashed a spore on fellow Sionnu members and escaped with three unhatched spore.[2]
He hired UNa to pilot the Nebula Left to bring him back to his Science Council Homeworld. However, they were betrayed by a crewmember and UNa was killed by Ryleth. Primor was able to retrieve the Gateway Access Key and escape Ryleth with the rest of the Nebula Left crew and headed towards his homeland.[1]
As they traveled to the homeworld, they were pursued by Ryleth. Ryleth secretly attached himself to the bottom of the Nebula Left and called in to the Sionnu about their arrival. They soon passed through the gate. They were shocked to find Sionox waiting for them with a battalion of Sionnu warships.[3] The crew agreed to turn Primor over to the Sionnu. Instead of agreeing, Primor ran away. He headed to the warhead room and launched several Spores to the Sionnu homeworld and set one off on the ship, effectively killing everyone.[4]
