I chose Gifted Mortal - here's my basic concept:
In 1307, the Knights Templar were destroyed. Except for 13 knights who were on a mission in Anatolia hunting for a mysterious murderer. As Jacques deMolay was being burned alive, he appeared before the leading knight - they were to remain hidden from view and they were to protect all men, enlarging their original charge. There were to be only 13 Knights, any one could become a Knight and they were to fight the darkness, wherever it threatened.
They were granted two gifts: they could heal faster than other humans, and their timeframe was 7:1. (Every 7 days was equal to 1 for the Knights - but they visibly age.) They were not immortal, though.
Over time, they built up a world wide network of support and each Knight has primary care of a region of the world. The 13 current knights include many different religions and ethnic backgrounds.
The PC is the *youngest* Knight, and he covers a large portion of the southern US and parts of Mexico - and things are going a little haywire, so he begins to work with some people he knows and trusts...
