King Heort was a Viking king who secretly used the black magic stone to rule his kingdom. Although he was mighty leader, there are only sketchy details about this King's history. In the Tome of Ezekiel it is said that, his legend will be immortal, for death shall respect his sons. King Heort was guarded by the legendary Beowulf, and his statue was placed as a key to open a way to King's tomb.
King Heort must have used the power of the Black Stone, magic that can raise the dead. This would explain why he is remembered only in grim legends and in the Tome of Ezekiel. The Black Stone were believed to be buried with King Heort in his coffin at the Wolf Fang's Peak. But there were only symbols there, the symbols helped decipher a part of the Tome of Ezekiel.
