After the tremendous success of the Epsilon sword, only one person was left who understood how to make energy swords. This is largely due to the scientists testing the swords on one another in an effort to create the best product possible (and to keep all the profit for themselves). The last scientist left standing created only 200 of these before he was spawn killed by a noob holding his own sword.
