Humans

Humans are a costant feature in the leagacy of kain and have been both allies and enemies of both Raziel and Kain,the have the potential to become extremely powerful sorcerers and have even been able to almost wipe out the vampire race twice even thought the vampires are the humans natural predators. All vampires after the Vampire/Hylden war were born human and were turned into Vampires

Blood Omen Era In blood omen humans were the ruling race as the vampires population was recovering from the sarafan crusade and were unapposed.The two main political powers mentioned in the game were the legions of the nemisis and the kingdom of willendorf,however each of the guardians had become legends in the own right and had aquired a large amount of followers(mortanius lead the worship of Has'ah'gik in avernus catacombs and mobius was able to rally a crusade against vampires even more succesful than the sarafan themselves). Near the end of Blood omen the human humans had left kain the only vampire alive.

 Soulreaver Era When kain began establishing his empire he destroyed all the human kingdoms and outlawed sorcery and enslaved many of them leaving only a few small pockets of resistance,the humans power over the land had been effectively broken.However the still proved to have some strenght left such as gathering together and nearly wiping out the third most powerful vampire clan and even phyiscal killing the vampire Dumah,They were also able to build a citadel which was architected to keep the vampires out,however this may have been a clever way of controling the human population as the city was secrety ruled by the powerful high priestess, who had learned sorcery from the vampires possibly Kain himself, and the vampire worshippers,however she was never featured in the game she was a very popular character
