The characters arrive in Thaliost, a city rife with unresolved tensions from the Last War. Through danger and discovery, the party will discover that the Lammanian artifact they were sent to escort back to Sharn has been stolen. They’ll have to track down the thief, who jumps onto the Five Nations Express, House Orien’s flagship lightning rail service, in a bid to escape to the Eldeen Reaches and open a gate to apocalypse.

The characters, members of the Clifftop Adventurers’ Guild, have been tasked with acquiring the Chains of Mur’taal, an artifact tied to Thelanis, by their guild handler, Lhara. This artifact is the latest in a series that Provost Nigel Faurious has commissioned the Clifftop guild to retrieve for him. The adventure starts when the characters arrive in Rhukaan Draal via Orien caravan. They’re given a chance to explore a small portion of the city before they head to a local bar to meet their contact provided by Lhara. Accompanied by a local guide, they make their way to the Seawall Mountains, where they’ll have to follow clues and their intuition to find the Valley of the Hero, which conceals the artifact that they’ve been hired to obtain. In order to earn the artifact, characters must first pass three tests laid before them by the Story: The Test of Courage, the Challenge of Wisdom, and the Trial of Honor. Once they finish the tests and collect the artifact, the party heads back toward Rhukaan Draal. But there are Marguul forces in the area, and they don’t intend to let the heroes escape with a priceless piece of their folklore…
