From Destinypedia, the Destiny wiki
The Blighted Centurions are Taken Centurion seen in Vex captivity on Io. Once released, these Taken attempt to escape from their captors and hunters who've released them to collect their plunder. They also make an appearance in the first encounter in The Reckoning, where they attempt to block the way to the Bridge of Folly and guard the Counterfeit Phalanx.
