After Shaniko came through and crushed Tayke then tried to take over all of Martapa, the knowledge of the Library of Tayke was lost to the world, for the most part. Some of the knowledge was rescued by a single librarian and his family, though it was only a fraction of what they had. At this point, all contact with the original Tayke (see my fourth book...hehe), so there was no where to run to. They headed to a small village in the north, that lived in the caves along the coast. There he and his family copied every single scroll they had, though it did take time, and spread the knowledge to four winds. Copies of these scrolls can still be found in treasure troves, private libraries and ruins of villages and towns on the east side of the Tsalagi Mountains.
The library itself was burned to the ground, though the cellar below was not completely destroyed. If treasure hunters were to look around they would find a secret, magically hidden room in the cellar, (covered in debris and years of vegetation grown), and inside there is a small stash of scrolls. The contents are up to the GM, but some of the scrolls have ancient magic, some have some engineering skills, and some is history and geography. These are what the Tayke considered the most important so the GM should consider carefully what they put in.
