Legendary blades such as Excalibur, Durendal and Kusangi along with Muramasa were hard enough to come by. However 3 out of 4 was not such a bad ratio after all when it came to owning magical items. Durendal, Kusangi and Muramasa were currently in a museum on Nap under triple security glass, with laser cannons, an alarm and bullet proof glass. The whole nine yards. A use for the three swords had not been discovered yet since the inhabitants of the planet had all been evacuated before they could discern a use for those weapons.
One Warrior Human, specifically one of the Elite decided the WH Elite needed more exotic and more advanced technologies. So he teleported down and used his magic to create an EMP effect local only to the museum. With all the traps and the alarm disabled he went and snatched the 3 blades leaving replicas of them made by his own magic but with no enchantments on them in place of them. With that he teleported away.
