I've actually gotten an idea for this. Thief of Time, Timestealer, something like that. Doesn't really have a name. The idea is a character that actually uses years of life as a resource, spending the years of life they have and stealing years from other beings as a touch attack. They can then burn off their accumulated years to delay bad things (everything from status conditions to death), perform more actions, look through the past, and glimpse the future.

I want to make it so any race with a maximum lifespan can enter (no elans, no warforged, no killoren), but I don't know how to balance the abilities.
