Drogar Ratarok is the High Chieftain of the Blight Dominion.
Drogar Ratarok is the oldest Krogan in existence and his various cybernetic enhancements keeping him together and wrinkly exterior definitely shows that off. Still blessed with a strong body at nearly the age of two thousand, Ratarok is often seen decked out in full body armor, but shirtless in the heat of battle. He’s also often seen with his varren, Shira.
Little is known about Drogar Ratarok before the Blight Dominion, although he is known to be the oldest Krogan in existence.
With the announcement of the Genophage cure, many Krogans wanted more than just a cure, they wanted vengeance. Drogar Ratarok led a group of clans to form their own separatist movement, the Blight Dominion.
The Battle for Wrill
During the events of CSV Muramasa: The Battle for Wrill, Ratarok's son Drogar Tarok was killed by G.U.A.R.D.I.A.N. operatives. Ratarok himself was defeated in single combat by his brother Drogar Ravenor and extradited to a Council court for war crimes charges.
