Popularly known as "Thorwald the Cautious." He was the fourth Emperor & High King of Faerie. Thorwald was obsessed with Truth and Order. He established standard weights and measures throughout the Empire, minted reliable coinage, founded the Office of Definitive Veracity, and formally codified into law many traditional practices (the most famous and fundamental of which is known as "Thorwald's Edict").

Thorwald died without a male heir, and was succeeded by his wife, Empress Greta the Feminine.
