An epigraph from Navani outlines a Fused metal that conducts Stormlight and a theory of an Investiture differential—removing Light from a full gemstone to create a vacuum effect—though the concept remains unproven.

Kaladin travels via Oathgate to the Shattered Plains, greets Navani’s flying platform of Hearthstone refugees, and escorts them to Urithiru. He wrestles with post-command options—rejecting diplomacy—and decides to focus on helping his people settle, guiding his parents through the tower’s peculiar architecture and planned neighborhood layout with shared balconies and common spaces.

Kaladin reveals a reserved suite: books for Hesina, a nursery for Oroden, and a fully stocked surgery for Lirin—complete with advanced tools and new medications sourced from Kharbranth, including reports of disease inoculation. Lirin, worried Radiant healing has made surgeons obsolete, is reminded by Kaladin that healing Radiants are few, have limits (no help for old wounds), and that Urithiru’s clinic is busy. Reassured, Lirin grows enthusiastic about the work ahead.

Prompted by Syl, Kaladin tells his parents he is leaving the military by Dalinar’s order and seeking a new path. Lirin, overjoyed, assumes Kaladin will finally become a surgeon; Kaladin accepts, committing to continue his surgical training and turning from soldier to healer.
