Legacy of Kain Wiki:Artemus

 Artemis was a nobleman  who appeared in Blood Omen 2. He had some sort of unknown business in the Sarafan Keep. He was valuable enough to be escorted by Sarafan Knights.

Kain was met by a woman in the Sarafan Keep who claimed to work for The Cabal, she refused to open a Ward Gate until Kain had dealt with the nobleman Artemis, who had apparently caused enormous harm to the Cabal. Kain found and killed Artemis and his Sarafan protectors before returning to the woman who opened the ward gate and walking off.
