Our Foundation, through extensive research on your Thunderstone tesla coils have realized that Thunderstone is not of this universe. We know not of which universe it comes from, but we have begun exploration/mining expeditions into every dimension in the multiverse. It will take a while, but please assist if you can.
This sounds very interesting... maybe the lightning contain so much power it opens a hole in space-time?
Whew, that's a lot... *Pulls out space-calculator* That will be... 15000 pix please! Enjoy your purchase!
We have determined that there is a growing mass of Thunderstone in one dimension. It keeps reaching critical mass and reaching Planck energy and opening a hole in spacetime. It sucks in a bit of it, reducing the mass from critical and closing the portal. Then it starts growing again, thereby repeating the process. Further investigation is being carried out.
