Kallias was an ancient vampire who lived in a crypt hidden in the swamps. Legend says Saint Mihai fought him, and the corruption he left behind still marks the bog.
Kallias was a vrakhir with an unusually deep link to Anachora. His hunting and his dabbling in dark arts drew attention, and Tobias and Mihai were sent to stop him.
Anything he slashed, tree or human, was overtaken by red growths. That makes the places he fought dangerous long after he was gone.
The fight moved to his lair. It is unclear whether Mihai killed Kallias or sealed him in his crypt, but either way Kallias eventually died, and his body became a source of corruption.
