In a fantastical medieval Estonia, Leemet grows up in the forest learning snakish from his uncle Vootele. Snakish is a hissing language that makes animals obey, so a hunter can simply call a deer to come and be killed.
The Frog of the North, a giant creature that once defended the land, can only be woken by thousands of voices speaking snakish together. No single speaker, however fluent, can summon it. A culture's most powerful capacities are collective, so they vanish once practitioners fall below a threshold, long before the last individual dies.
The villagers give up an effortless life, in which they called game to them, for backbreaking farming, sickles and foreign priests, because the new ways look modern and belong to admired outsiders. Seen this way, many transitions labeled progress are status imitation: people accept worse outcomes to look up-to-date and to avoid seeming backward.
The book does not romanticize the forest. Clinging to tradition as dogma kills the same things that thoughtless abandonment kills, and the sympathetic figure is the one who keeps a living skill without worshipping the past.
Leemet grows up in a forest where people command animals with Snakish hisses. Wolves are milked, deer come to be slaughtered, and bears court human women. As his kin move to villages to grow grain, eat bread and serve German knights and monks, fewer people remain who speak the language. Leemet is left the last speaker, and the legendary Frog of the North, which can only be woken by thousands hissing together, can no longer be roused.
The novel refuses to make the forest the pure good side. Its keeper of the sacred grove, Ülgas, is a bloodthirsty fanatic, and the forest has its own superstitions and cruelties. The villagers' fawning Christianity is just as credulous. The claim is that dogmatic nostalgia and dogmatic novelty-worship share a mechanism: each surrenders judgment to an authority. The loss worth mourning is the practical, living knowledge, not either camp's ideology.
