19: An Extinction-Level Event (say, a freekin' big meteor hitting the planet) threatens human civilization.
20: That wasn't just a metor, it was a magical meteor! The Ethereal shockwave has (temporarily?) cut off all dimensional travel, and caused the world's magic to go wonky -- wild magic zones appear like thunderstorms, and impeded and dead magic zones are growing like deserts. Acid and fire rain from the sky, and demons and yugoloths rage across the land.
21: That wasn't just a magical meteor... it was an Ancient Evil from the Outer Darkness -- an Atropol / Infernal / Phaethon / Xixecal / Ancient Force Dragon (with Shadow template, of course) / Mu Spore / Pseudonatural Tarrasque / Vermiurge, or something like that.
22: That wasn't an accidental Ancient Evil from the Outer Darkness, it was summoned by someone who wants to use it to stop what they perceive as an even greater threat... even if it means sacrificing every living being on the planet. (This "person" would probably be undead, or a very devout worshipper of Orcus.)
-- N, not currently doing all of the above to his 10th level PCs, especially if they're reading this!!!
