Vekker, a male Quarren, held the Vigo rank within the Black Sun syndicate during the period when Prince Xizor was in control.
Xizor recognized him as someone who was satisfied with his current position and lacked any desire for advancement within the group. Vekker attended the Vigo's meeting where Guri openly killed Vigo Green for acting as a spy for an external party.
Following Xizor's demise in the Battle over Coruscant, Black Sun was nearing an internal conflict among its criminal elements. The Vigos convened a council, during which Vekker was observed having a heated discussion with Sprax.
Savan orchestrated a false attack on the Vigos and implicated Vekker, thereby initiating a conflict. Shortly thereafter, Vekker was pursued and met his end in 4 ABY.
Vekker's name originated from a predatory creature that is indigenous to Dac.
