Since artifacts were so rare, it was always big news when one went up for auction. Some had been known to sell for hundreds of thousands of credits, depending on their powers. The record had been set three years ago when an artifact called the Cataclyst was auctioned off. According to its auction listing, the Cataclyst was a sort of magical bomb, and it could be used only once. When it was detonated, it would kill every single avatar and NPC in the sector, including its owner. There was no defense against it. If you were unlucky enough to be in the same sector when it went off, you were a goner, regardless of how powerful or well protected you were.
