Absolution was a story arc that centered around Dahlia Cortez, and her lifelong quest for revenge against the men who ruined her life; her brothers.
The arc immidiately followed the Tsunami, and began with the capture of James Price by the Widow Pirates.
It followed and focused on the time Tara Anders spent onboard The White Widow, as she willingly gave herself over in exchange for the Grand Commander's safe return. Varryk made his first appearance in a story arc since his "resurrection", and was a prisoner onboard.
The climax was when Dahlia finally slew her brother, and had a very emotional finale that showed the infamous Pirate Mistress in very, very different lighting.
