The Hollow Throne has found something unbelievable: a mortal-made compound that can halt the Weeping Thorn’s spreading corruption. To get more of it, they summon one skilled craftsperson from every village. Thrium Cloudstem wants nothing to do with the summons, but he’s chosen anyway—and forced to swallow a strange twin‑berry meant to grant him a clean, official class.
