Olgierd von Everec is the secondary antagonist of Witcher 3: Hearts of Stone. Olgierd is an arrogant Redanian noble, who wanted to marry Iris but their parents didn't allow for this due to his bandit lifestyle and poverty. They arranged marriage with an exotic prince instead.
He was voiced by Paul Thornley.
Olgierd made a deal with Gaunter O'Dimm to become immortal, so he could restore his fortune and marry Iris. To do this he sacrificed his brother and magically changed to prince into a toad monster and imprisoned him in sewers.
He succeeded but began to lose empathy and other emotions. Because Iris isn't immortal and age he imprisoned her in a different magical dimension to keep her alive.
He has to fulfill his part of the deal with Gaunter so he asks different people to make impossible tasks for him. Geralt of Rivia is one of them. The witcher has to give his dead brother a fun he never experienced alive, to reclaim a box from Horst Borsodi and to bring the purple rose the nobleman gave to his love Iris.
- Olgierd is similar to Philip Strenger from the main game. Despite far from being good, they hide a tragic backstory and are more morally flawed than evil.
