I wonder how Albion was the place that multiple copies of this book was there. If it was such a priority to obtain, there must be other copies in other spires. It would be easie to get than enemy territory. Sure they wanted to destroy every copy there, so why not take them with you. That way Albion has none, while they have many. With the destruction of the library, and death of its keepers, no one could say it survived.
