Giants have emerged from their strongholds to threaten civilization like never before. Hill giants steal all the grain and livestock they can, while stone giants roam settlements that have been around forever. The fire giants drive the peoples unable to defend themselves  into the desert, while the longships of the frost giants plunder the entire Sword Coast. Même les géants des nuages ​​insaisissables ont été vus, leurs merveilleuses villes flottantes apparaissant au-dessus de Waterdeep et de Baldur's Gate. Where is the storm giant King Hekaton, who is responsible for keeping order among the giants?
 
Humans, dwarves, elves and other small people of the Sword Coast will be crushed by the onslaught of these giant enemies. The only chance of survival is for the lesser peoples to work together to investigate this invasion and harness the power of rune magic, the weapon of the giants, against their ancient enemies, the dragons. The only way for the people of Faerûn to restore order is to use the power of the giants against them.
