I’d never seen the sky without a shield occluding it. It hadn’t been disabled during my lifetime. Without it, we were vulnerable. Not just to rain and snow, but to a far more terrifying prospect. Invasion. Keeping the elements off of us was the practical application of the barrier, but it served a more important function on the international scale. It blocked a vast variety of foreign spells from getting into the city. Scrying, teleportation, artillery spells — it was an effective tool against both reconnaissance and direct attacks. And it was gone.
