When the walls come tumbling down...

[Argent Silvermage]

Time and space rip appart and the world becomes a "hub" for planer travel. The bounderies become so weak that there are now permanant (but not stable) holes to other worlds. This of course leads to a planetary invasion from a wholley unknown enemy.

My campaign world has just been hit with an Extinction-Level Event in the form of a big SOMETHING that hit the large ocean from Somewhere Above. Sea level is significantly lower, and carbonic acid rain has been falling for three weeks now with no end in sight.

Good: It's a very different world, and the PCs are struggling with the environment as much as with the monsters. Food is significantly harder to come by. They're releived to be spending a month in Gehenna.

Bad: The night sky is obscured (well, all the time the sky's obscured), so celestial events aren't gonna be easy to spot.

Deeply Frightening: The world's ecosystems are ravaged. It's a great time for an insidious invader to make its move...

Alright, a combination it's going to be... Primary will be a Global Shifting of Tectonic Plates. This will cause a major world-wide earthquake, with the following effects:

• Several major population centers will be devestated, including the "target city".
• Seas will drain and mountains will fall, with other mountains rising and new seas forming.
• Aftershocks that will last for several months, with some fault-lines remaining high-pressure
• Many places will flood, at least temporarily (around the city that is the object of this thread, this is temporary, but will shatter the heated barerock of the region, thus providing many obstacles for the on-the-march army)
• The earthquakes will also crack and shatter most of a glaciers; combined with global-warming via greenhouse gasses released from newly-active volcanos and warming seas, the ice will begin to melt at an accellerated rate, bringing about the eventual end of the "Age of Frost" within a decade or two.
• There will be meteors, sometimes small ones in "showers" and sometimes a single big fireball. No deep impact, but devestating to the local region (possibility: several showers but only one "big one" which creates a new wasteland or perhaps a very "alien" landscape). Not sure how to handle yet; Not likely all on the one day, but perhaps during the next year or three as a "trickle down" effect of damage caused to the heavens (time to finally read When the Sky Falls...). Some of these will likely be responsible for the occurance of bizarre magical mishaps (wild magic, over-lapping dimensions, Tesserrerracts <sp?>, dead magic, etc.) and a minor influx of epic-powered magic items (next millenium's artifacts).

Wow... And I'm going to need a new map...

Planar-boundary stuff is possible, but I'll likely hold on putting thought into that for now. That would be getting close to the extreme-end of the clock being "unwound" too long. About mid-point, though, I'd likely lean towards inter-dimensional prisons, objects, and spells starting to malfunction (demons escape, harder to put them back, plenty of cult-worship fodder for the next few centuries).
