Written history

In a world that is constantly wrecked by war, it is considered very difficult to keep proper written records of everything. Most nations are too focused on protecting their own borders, or attacking their neighbours, that the only written records they keep are reports, population censuses, and obituaries. While these documents are indeed precious to establish facts, they hardly substitute proper historical writings. Worse; since most of the written documents are of a military nature, they are the prime target for intelligence operations and "accidental" fires, meaning that a lot of it is lost to the nature of war.
One Veika, however, feels differently. Eolas has retreated from the rest of Domhan, isolating himself in the center of the Silent Desert, and opting to make sure that an accurate historical record of this plane and its wars is kept. Within the mysterious Grand Library, monks of all sorts classify, sort, and clean all of the books, parchments, records, censuses, charts, chronicles, legends, and all sorts of written records besides. Most are originals; some are copies. Nonetheless, it is said that if it is not in the Grand Library, it does not exist - leading some to believe that Eolas may know about Ako's true identity, and its current location.
In order to keep such accurate records, Eolas sends specially-selected Emberi, Eolians, out to the world. These monks are very secretive, effectively half-spy, half-diplomat.
Other nations are jealous of Eolas' historical records, though mostly for selfish reasons. Only Gestrini is happy to help Eolians, and often welcomes them within their haven of peace. Ironically, BECAUSE Gestrini is so calm, Eolians often avoid the place, preferring to be where history is happening: at the front lines.
Even though written records are rare, most Emberi are still able to read and write. This is because most can call upon the memories of their former lives; or visit specialised establishments designed to help them remember.
