When the Sky Falls Web Enhancement by Monte Cook
The sky has fallen. The fist of the gods has struck the earth and now all is in chaos. The skies grow dark and the displaced survivors seek shelter. But who will save the living when they are preyed upon by the dead?
This web enhancement for When the Sky Falls is an expanded adventure seed suitable for four 4th- to 5th-level player characters. It provides a strong skeleton for an adventure, but relies heavily on information found in When the Sky Falls by Bruce R. Cordell. DMs should flesh it out with place names, relevant nonplayer characters, and additional content as necessary to insert it into their own games.
Not only can DMs use this scenario as a miniadventure unto itself, it also provides plenty of mood and atmosphere details for roleplaying in the aftermath of a meteorite impact. The threats characters face at a time like this need not be supernatural to be a challenge. No matter what type of meteor strikes in your campaign - mundane, thaumaturgic, or engram ark - issues will arise that require the PCs to deal with refugees, overcrowding, con men, and chicanery.
