Relic

An exceptionally old stone giant calling himself "Relic", he is the vampiric lord of the southern marshlands of Kapaerian Island.
A staunch follower of Adaxus, he was a Sul'at League wizard who worked for Adaxus back during his life. When the giant's empire was destroyed, he embraced his necromantic specialization to accept the curse of vampirism, surviving the cataclysm. Since then, he has become increasingly unstable, alternating between centuries-long sleep and violent domination of the surrounding villages. In modern times, he teaches magic to the local giant villages, embraces his favourite students as vampiric thralls, and installs them as local leaders to do his bidding, a pale imitation of the empire he lost. 
Relic was finally slain by the heroes of Beacon, lured back to his lair by taking advantage of his paranoia and instability, then killed before he could rally his full forces to bear.
