Grandmaster Fredrietch Kalven, a researcher of lost arts, was tasked by the king to find and record all written histories of their world since the earliest writings.
After many years of research and studies, Fredrietch compiled the written works he collected from ancient libraries, buried ruins, heirlooms from noble houses, and oral passages from tribal natives. The Chronicles of History was later finished after the Grandmaster's death.
How did these written materials such as scrolls, codices, and tomes survive after 3000 years after wars and calamities, especially in those ancient libraries and ruins?
Magic exist in this world and only elves can wield it. Magic that has been cast as an enchantment, will loss its effect because of magic decay.
