[@lydyn] Romance is allowed. Feel free to try and romance any of my characters. As for Guardians, there are people born with supernatural powers. They can have anything that doesn't give full control over an element. They can also use certain types of magic, such as Necromancy, Blood Magic and Voodoo. 

Guardians can be done several ways. A guardian may know the prophecy, and therefore, know that they are destined to be a guardian one day, they may decide to seek out the elemental ones. 

Or, they may know about their powers but not of the prophecy. The reverse could be true too. Or could you have it so they haven't discovered their power yet and will have them discover it in the Rp.

[@Nerevarine] It is an interesting idea, but it won't play out very well, as not many people will state their will power. So it will be hard to determine who is stronger, and honestly, I don't see it being used much. 

[@RangingWolf] This is an original idea. Although, there are a few versions of it, as it has been remade a few times.
