Tears of the Burning Sky (5E)

From publisher blurb: Into The Fire In search of the Torch of the Burning Sky, the heroes set out for Sindaire and Castle Korstull, the canyon fortress where Emperor Drakus Coaltongue was slain. Their destination lies within an endless firestorm, the result of a peculiar rupture in the fabric of the planes. While the castle surely holds clues to the fate of the emperor and his torch, the heroes will have to contend with fiends, rival treasure hunters, and the survivors of Coaltongue’s army to learn them. Might the torch itself lie in Castle Korstull? What happened to Emperor Coaltongue, and what strange magic brought forth the tears of the Burning Sky? A 5E fantasy adventure for 11th-level characters.
