I'm sure theoretically they do but.... its not like we're gonna go to the Keepers and watch them rempower the aspects again. Not necessarily because they need anything in particular. No, if they are to get empowered, something is going to cause a distraction delaying said empowerment.You know, thinking about this, it's quite weird that they don't just consult the other keepers about it.
Surely they would have *some* idea on how to repower them.
