Rieltar Anchev

Rieltar Anchev (sometimes spelled Reiltar) was the regional leader of the Iron Throne in Baldur's Gate, and the foster father of Sarevok. He killed his wife in front of Sarevok when he was young. He was also a central figure in orchestrating the iron crisis to gain power to the Iron Throne, as well as the doppelganger infiltration of merchant rivals. He was unaware that Sarevok was planning to use the crisis to his own benefit. He intended to use the ensuing war with Amn to cause monumental slaughter that would cause him to ascend as the new Lord of Murder, taking after his real father.

When Rieltar and Brunos Costak are negotiating a deal with the Knights of the Shield in Candlekeep, Sarevok goads the player character to take this opportunity to take out the leaders of the Iron Throne. If he doesn't succeed, he simply has dopplegangers do it in their stead, disguised as the player's party so that they get arrested for murder anyway.
