Worldfall

A worldfall was an occurrence where the planar energies of the multiverse aligned in such a way that large areas of land―or even entire cities―could transfer from one plane of existence to another.

Description
Whenever a worldfall occurred, anyone within the affected area were transported along with the surrounding terrain.

Activities
Cities built by the eladrin often utilized worldfalls to travel to and from the Feywild.

Notable Worldfalls

 * Shinaelestra, the eladrin city that shifted away to the Howling Forest on some unknown world at midnight every day, and returned to the Feywild at dawn.
