turn back time.

you touch an item and travel backwards through time with that item. for however long you travel backwards, you age that much. for example, say someone assassinating a king 5 years ago started the apocalypse. you touch a tree that is 100 years old you go back in time 5 years to the same spot, but the tree is 5 years younger, and you are 5 years older. you can then stop the Assasin and stop the apocalypse. after your time travel mission is complete, you will go back to your own time, but the past will be altered and you are still 5 years older.

the side effect of using this power is that after using it for the first time you can only talk and move backwards.
