Interesting concept. How is it balanced out? What are the disadvantages? How is it "fueled"?

just noting down listed abilities:
Predict future
Aging non-animate objects rapidly to point of disintegration
Turning back time on some objects
Short-term time stops

The aging one seems the one with greatest potential for being overpowered. It needs some means of limiting itself. Perhaps related to how the relic is "fueled"?
Also, the short-term time stop doesn't entirely make sense. Perhaps replace it with something about him tweaking time to seemingly blink across greater distances, but keeping the limiter of once every [i]n[/i] days at best.
