A terrible threat gathers in the North. Throughout this region of the Forgotten Realms, savage marauders bring destruction. Monsters are on the prowl, preying on flocks, rampaging through croplands, and attacking homesteads and travelers. In settlements, discord and suspicion grow. Sinister strangers lurk in the shadows, whispering about how everything is soon to change.

The threat of Elemental Evil surfaces in different
worlds of the multiverse whenever the force known as
the Elder Elemental Eye tests its strength. Servants of
this malevolence seek to master elemental magic and
unleash its destructive power everywhere. In its current
incarnation, Elemental Evil arises in the Sumber
Hills of Faerûn—the world of the Forgotten Realms.
The scattered towns and isolated homesteads of this
frontier now face a dire threat. If the forces of Elemental
Evil can’t be defeated before they grow, madness and
destruction could spread unchecked through the North.

Called by the Elder Elemental Eye to serve, four corrupt prophets have risen from the depths of anonymity to claim mighty weapons with direct links to the power of the elemental princes. Each of these prophets has assembled a cadre of cultists and creatures to serve them in the construction of four elemental temples of lethal design. It is up to adventurers from heroic factions such as the Emerald Enclave and the Order of the Gauntlet to discover where the true power of each prophet lay, and dismantle it before it comes boiling up to obliterate the Realms.
