Dungeons: An Alternative View

Neferu of the Seven Burdens proposes that dungeons represent a system of reproduction and adoption for magic swords. She asserts that adventurers go into dungeons, find treasure, and then spend it, causing normal swords to be forged. These adventurers eventually die in a dungeon, where their normal swords can soak up magic until they become sentient. This will attract more adventurers hoping to gain possession of the magic sword, allowing the sword to make its way into the world.
