Vesina
From The Stargate Omnipedia
Alias used by con artist Vala Mal Doran when she visited Grannus's monastery. "Sister Vesina" would occasionally trade with "Brother Caius" (a smuggler) on the inside. She provided the monastery with a cargo ship's power coil, which the monks dubbed the "Ring of Shen-Marak" and venerated as a holy relic.
