Throughout history, the concept of the ‘lost city’ has always fascinated… likewise generations of gamers have been drawn to explore by legend and rumour, right back to the Basic Dungeons and Dragons module B4: Lost City! Whether it’s fame and fortune, mere survival, or some higher purpose, mention lost cities and adventurers will come in droves. This lost city is no different, and there are wonders to discover for those brave enough and skilful enough to explore.

The lost city of Kadralhu has much to offer the adventurer and much also to offer the gaming group, for it is presented as a ‘sandbox’ adventure, a setting with much to do rather than a single plotline to figure out. Whatever the characters’ motivation for going there, wherever they venture once they arrive, there are things going on, things to discover, enemies to vanquish, allies to be made and secrets to learn.

The Plane Below greatly expands on the Elemental Chaos, which is one of the fundamental planes of the Dungeons & Dragons 4th Edition cosmos. To be sure, this supplement is primarily intended for Dungeon Masters and is best suited for paragon and epic tier games. There is no doubt that the Elemental Chaos is aptly named, for although there are some relatively stable places to visit, much of the plane is filled with a roiling chaos of raw elements from which the rest of creation is derived. It is a hostile and alien place — just the sort of place to drop your players into unexpectedly to watch them squirm.
