All power corrupts, as the saying goes, and absolute power corrupts absolutely. And what could be more absolute than the ability to rewrite the very fabric of existence?
The Grave Callers are presumably a shadowy cabal of arcane users who manipulate world events behind the scenes for their own good. Sometimes, they are portrayed as a defender of justice, fighting corruption within the ranks of the many politicians, bureaucrats and nobles running the affairs of Altier Valley. Other times, they are spoken of as a selfish, amoral group of wizards who lost their humanity by dabbling too much in power too intoxicating for a mortal’s good.
Whoever they are, many of their myths, stories and urban legends revolve around the College of Five Colors, no doubt because it is the premier center of arcane knowledge and research in all the valley. It is even rumored that Professor Mandius is a member of this organization, though no one can, or will every try to, prove it. Whoever they are, they remain a secret, as well as a fairy tale to keep more than just children in line. Sometimes the mere threat of a “visit” from the Grave Callers will scare a senator or corrupt official into the “right path” once more, at least for a little while.
