The Twilight Caste are the scholars, sorcerers, and craftsmen of the Unconquered Sun. In the First Age, the Copper Spiders were the creators of fantastic wonders and artifacts, as well as defenders that relied on cunning and magic. The Unconquered Sun rarely chooses withered scholars who have poured the years of their life into the pages of dusty tomes. Instead, the Arrows of Heaven are scavengers, engineers, healers, detectives, thaumaturges and artisans who use their knowledge to accomplish impressive results. They possess not just a thirst for knowledge, but also a burning desire to use it.
