In Episode 14: Into the Blacklands, the road north becomes a furnace.

Apple, Sebastian, Wyn, and Halen push deeper into the ash-choked Blacklands, where cracked stone hides killing heat, ruined roads lead toward dead cities, and every breath tastes of sulfur. After rescuing two surviving Iron Graspers from a brutal fire cult, the party learns that Malrick has already reached the ruins of Glarus—and taken something he should never have found.

An Emberkin egg.

Guided by grief, urgency, and the possibility of more prisoners still alive, the party crosses lava fields, black glass ridges, and the haunted remains of a city swallowed by fire. But when Halen discovers a hidden clutch of black-red geode eggs near a lava pool, one terrible mistake awakens an ancient ward.
