Grand Library

The Grand Library is a massive library said to be hidden beneath the capital city of the elves, Prifddinas.

The Grand Library is said to contain vast knowledge, and many secrets that have never fallen into the hands of humans. Although almost nothing is known about its actual contents, it is understood that it was one of the key factors in allowing the elves to survive the early years of Gielinor, after they entered through the World Gate. It provided them with the knowledge to create Prifddinas, amongst other things.

When the God Wars drew to a close, the elven goddess, Seren, was forced to depart from Gielinor. However, since she feared that the knowledge of the library could fall into the wrong hands without her there to physically protect it, she sealed the Grand Library. It is now protected by nine powerful seals, and there is no known way to break them.

Iestin told his brother that he believed that one of these seals may have been broken (see Edern's journal). It may have been done by the clan of Lord Iorwerth, although how they accomplished this and for what reason is unknown.
