Artifact

An Artifact is a relic of magical power. They are incredibly rare and in an indeterminate amount. Each represents a fraction of some magical being's power, having absorbed it through extensive contact with the original owner. Whoever owns one can use that power for themselves.

Artifact Quest
An Artifact Quest is a special type of mission with the goal of obtaining an Artifact for personal use. At the cost of five Souls, a character can undertake a more difficult mission for the chance at finding the Artifact. The chances of death and/or failure are intentionally high, as Artifacts are immensely powerful. If a character were to fail but survive, they would not be refunded their Souls.
