The heroes of Phandalin have braved a Netherese ruin and traversed a collapsing pocket dimension to find themselves at the heart of the city of Xandril in the chamber of the Mythallar. There, they must face not only the cabal of Red Wizards that control the artifact, but the nefarious Stormfire siblings.
The heroes venture into an Uthgardt settlement, now ruined, in search of the Emerald Enclave. Thundertree it seems, is home to several factions - dark druids, red wizards and a green dragon!
Beneath Dragon Barrow lies a secret, the lair of a dragon long thought slain, but now an undead horror. It's influence in the Phandalin region has been subtle but malignant, through cursed weapons and horrid visions. Now, the heroes of Phandalin, wearied by the trials of Tanamere's Tomb, must face it's fina challenge, Azarzhel, the Storm of Swords
Below the a burial mound in the foothills along the High Road lies the tomb of Lady Tanamere Alagondar, a knight who slew the dragon Azarzhel, the Storm of Swords. The Heroes of Phandalin have run off the red wizard Hamun Kost as he attempted to gain entry using a mob of zombies. Now they seek to retrieve Lady Tanamere's sword, a weapon enchanted against dragonkind that will aid them in slaying Cryovain.
The heroes have choices to make and need to come up with a plan. The people of Phandalin need to evacuate - the joint dangers of orcs and the dragon put too many lives at risk. The orcs have captured several townsfolk - who will rescue them? The orcs seek the Crown of Horns, Uruth Ukrypts crown would grant them great power - how will it be denied them? Sir Leoric is stll dreamy, how will the party cope?
