I have this idea about a land’s source of power.
what do you think about land’s source of power is crystals but made from magic in order to speed up the time it takes to make one naturally same with diamonds.
but this source is mostly from pink crystals (or any other colour depending on the task) and thanks to the magic of witches it has amazing powers such as
————————————————————————————————————————————————————————————————
making portals and transporting entire towns to a new location
(but several witches have to make the magic that powerful so is rare if used at all the only case is for transporting old towns to new locations so the residents can have a new home without leaving what they had in order to inhabit a new land)
electricity for cars and a train as well as general electricity for everyday use. they levitate off the ground so there is really no need for a railroad (except for a set path which is colour blue for the blue or Agate crystal it has)
for cars they don’t levitate except during winter in order to prevent accidents
they can be used to light up the land (they are white in colour)
and to warn of any intruder witch will turn red and signal the guards depending on the area
and just the magic, in general, for the edges of the land, makes a fog for any harmless normal pony so they can get through the forest or sea without seeing the town or the new land unless they are special (as in they are willing to be understanding and the crystal can sense that)
this magic last forever though every ten years a few witches who knows the spell will refresh the main crystal that is somewhere in the middle of the land hidden away in a cave in a town with a national park where and is a big event done in the new year of the new decade
how does that sound so far?
