The Order Scorpius are a sect of assassins maintained by the Berbary States. The Order's assassins are deployed in pairs - with the Order preferring twins to sew doubt and confusion amongst their enemies.
The Order was dispatched to assassinate Jasmijn Vahl in Mondoza, but she was removed by Gabriel de la Cruz. They did strike against Hubert Messier, blinding him. They still consider Vahl as a contract outstanding.
