The World of Ice and Fire (mentioned)
Archmaester Perestan is one of the archmaesters at the Citadel. He has a poor opinion of Archmaester Marwyn. He claims the world is forty thousand years old. He teaches history at the Citadel. His ring, rod and mask are made of copper.
He considers that the importance the Norvoshi give to the axe as a symbol of power and might is proof that the Andals were the first to settle Norvos, and suggests the bearded priests took the emblem from ruins they found as they established the city. He argues that axes are, next to the seven-pointed star, the second most common symbols favored by the Andals warriors who conquered the Seven Kingdoms.
