Gaerlan was a mage of the Yalain Empire, and a student of Asheron's. He and his brother Delacim studied portal magic and other arts under Asheron's tutelage. During one of his explorations, he discovered a library (Gelidite Library from its description) with ancient Falatacot books. He started cataloging and translating these books in service of Emperor Kellin II. He also discovered the remnants of a Gelid elemental cult flying fortress off the coast of Aerlinthe, and studied the magic that he found within another library, the Citadel Library, to look for a way to help the Yalaini and Haebrous against the Dericost.
