The Fountains Of Aescalon

What if the Connecticut Yankee In King Arthur's Court was a real wizard?

Alexan is exiled from his home for reasons of politics and health, sent to a primitive locale to guard against the misuse of the massive power coursing through the fabric of reality.  He discovers that he is what the locals call a wizard.  Unfortunately for him, there are many other wizards and even gods connected to this power, and they tend to be unfriendly to those they fear might rival or replace them – people such as Alexan.

And what about this demigoddess that keeps popping up with obscure hints about her divine curse?
