"Partisan" was the assumed name of a Mesan Alignment agent during Operation Janus, who pretended to work for the Star Empire of Manticore and stirred hopes in the Loomis Liberation League that the Manticorans would come to their assistance in their fight against Ailsa MacMinn's regime.

As of July 1921 AD, Partisan appeared to have sufficiently large workload that Isabel Bardasano planned to send Damien Harahap to assist him. (SI4, Ch 15)
