[@Balthazar007] What's the age limit? I was thinking of having someone with the inability to age and go through puberty.

There are no age limits. He/she can be as young or old as you want them to be. 

And I guess your ring could grant you the ability to not age, as you can absorb life force from others to stay young, but the way you made it sound is the character has that ability without the ring. That wouldn't be correct. The only magic in this RP comes from the rings. But I would like to assume that's what you meant in the first place.
