Jyll Xon was a secretary working in the Metatheran Cartel's operations office in Gadrin. When most of the Cartel's personnel had been transferred to their base in the jungle, she and her supervisor, Manod Fea, were the only employees working in those offices. Although Fea left the office for two hours every day, Xon remained there full-time. Xon wore a hidden transmitter on her left wrist that could summon Metatheran Cartel security forces.
