The HBO vampire series True Blood has made a habit out of landing high-profile guest stars. The upcoming Season 5 isn't shaping up to be any different, with Spartacus: Vengeance star Peter Mensah signing on for a recurring role.

The actor will portray Kibwe, who serves as Chancellor for The Authority. Originally hailing from Africa, Kibwe will try to mainstream the power of the organization. It isn't known how many episodes of True Blood Season 5 that Peter Mensah will appear in.
