One heard of such places, where elves did powerful spells. Secluded away from anything that could affect a spell, the sites rested on the intersection of strong ley lines, tapping directly into an incredible amount of power. Those ley lines were permanently carved into a floor of white marble. White to show the tracings of a spell. Stone to act as a natural insulator. The marble sat on limestone bedrock, and the wooden shelter was constructed with no nails, containing not a single scrap of metal.
