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.
