Thousands of years ago, a warrior named Backus crossed an ocean to gain access to an island fortress. Under cover of a dark thick fog, Backus crossed those deep blue waters in a wooden vessel captained by the sentinel of the island. He bribed the sentinel with a pouch of gold dust and, once upon the island, had to do battle with Fireon, the two-headed dragon.
No ordinary warrior could have even get past the sentinel, much less defeat Fireon, but Backus was no ordinary warrior. The gods had given him tools and magic that, coupled with his perseverance, enabled him to gain entry. When Backus finally came upon the treasure lair, he had to do battle, one last time, against Jiant, the ocean dwelling creature.
With a little ingenuity and the proper tools, Backus defeated this formidable foe. Did Backus take any of the treasure? No. Instead, he hacked off Jiant's head and returned home. The moral of the story is that even the most impenetrable security can be defeated.
