Storm King's Thunder
Having survived the unexpected encounter with the ancient red dragon known as Klauth, mostly by design it seems, Rock Band repaired their wayward airship and proceeded to the next sacred mounds. They gathered a couple more relics of Giantkind, avoiding a couple of curses in the process and taking stock of the fact that they are missing at least one of the five giant subspecies needed to open up every path.
But time has grown short. Harshnag, their ally frost giant, has been holding a vigil inside the portal to the Oracle of the All-Father for nearly a month. With no way to communicate to him, Rock Band must finish their explorations and reach the temple before its too late.
