It has been confirmed by EW that “former star of the Dick Wolf drama will join HBO’s ‘True Blood’ in season 5 as ‘ancient, powerful vampire who holds the fate of Bill and Eric in his hands.’ He will be a series regular.
Meloni’s role on Alan Ball’s drama marks a homecoming, of sorts: The actor previously played Chris Keller on the pay cabler’s gritty drama ‘Oz’ from 1998 to 2003.”
