Istman

Istman's first named appearances. "The youngest boy, Istman, whose birth had sparked the Greenflower Event was officially Dunselen and Isily's son, and would inherit Greenflower as a barony." He is a jolly boy even Alya enjoys, and his infant charms rekindle her desire for another baby.

Taren reveals the thaumaturgical significance: Istman's birth at Castle Salaisus produced Bluestone — a variant of the snowstone effect via calcium transmutation — confirming the Natal Spark theory. He lives at Greenflower Hall in Vanador with Ismina, under Taren's guardianship.

Taren reminisces to Lady Varen about caring for Istman through colic, jokingly saying he would have traded him for a piglet if he were not so cute. Taren expresses genuine affection for both Istman and Ismina. Istman's birth-event is repeatedly cited, alongside Minalyan's and Fallawen's twins, as a data point in the ongoing Bluestone / snowstone calcium-phosphorus-potassium experiments.

Minalan hugs Istman and Ismina tenderly after his disturbing Greenflower journey and encounter with Isily. He agonizes over whether he will ever be able to tell them that he killed their mother.
