Swelling, fading, and never was.

Flavia was thrilled.  The decision to travel to northwestern shore and build a tower there had proved correct. Every day she was making new discoveries in transforming materials. There was no telling how deep this convergence pool went.

Wonder of wonders. The light from the lantern spilled out across the dusty armory with glittering pricks of reflection. The tunnel Benth had discovered while exploring the ruins in the South Wood apparently had belonged to some long dead kingdom. Where else could such marvelous items of workmanship come from?

Gwyneth's hands quickly snapped up, nocking an arrow.  The band of brigands she was hunting were returning to farmstead they previously pillaged.  It wasn't her problem to fix, but when she would arrive at Lord Winston's home with an extra four scalps, there would definitely be an extra pouch of coin in thanks. Coin she needed since her horse had just been stolen in Shandon.

In trying to think about MW, I cant seem to decide on which direction magic is going.  Everything I think of seems derivative or cliche; it is too like Tolkien, or Jordan, or Gaiman. I want to have a world where not only no / low magic campaigns and adventures could take place, but also high magic.
My first thought was to have them to be time shifted along a spectrum, but then is that increasing, decreasing, or even cyclic in magical properties.

Currently I am toying with a cyclic plan, with the cycle to be too far beyond the generations of men to properly recall the time of high magic or prepare for the time of none. Nonhuman peoples perhaps do know of the cycles in better terms due to much longer lifespans, but keep this knowledge withheld. Magic must be earned so that the proper respect is given to it.  As magic is used, pools of it drain. When they dry, people cease and forget, allowing time for the pools to refill and replenish.
