The nails give way with a groan as the lid of the first crate is pried open revealing an abundant supply of legion gladii.  Opening further crates reveals other weapon caches containing composite longbows, pilums, daggers, long swords, and longspears.  All weapons designed to outfit a legion and are of masterwork quality bearing the same insignia as upon the box.  The padding of the box did wonders to keep the little moisture of the relatively dry cave from degrading the steel that has gone unmaintained for decades and it shouldn't take too much effort to restore them to pristine condition.
