Possessed best friend: Check.
Bargain with an angel: Check.
Sentenced to death: Check.
Said possessed friend saved: Kinda.
After the possession debacle Marcus Fadelocke earned the death sentence. But the date of his execution was not set and he was cursed with the status of Acribus, the Doomed.
For twenty years he will be sent on the most dangerous missions after which his sentence will be retried.

No rest for the wicked, or even the virtuous. What is a young Mage to do?
