Lirwon was a Tezwan who was employed by the government. He confirmed receipt of one of the contraband shipments sent by Presidential Chief of Staff Koll Azernal and Federation Minister of Military Intelligence Nelino Quafina; when he didn't get back in time, he and his team was found dead by Keena, likely killed by loyalist forces loyal to deposed Prime Minister Kinchawn, who intended to capture the shipments and use them to blackmail Bilok and the Federation.
