This is an RPG module which I wrote and have run several times.
In this module, the adventurers encounter a group of six evil artifact weapons, legacy of a great war that caused the extinction of the ancient draconian race. The artifact weapons are intelligent, and they seek the destruction of all life. Cultists foolishly seek to harness the power of the weapons for their own ends. The adventurers might attempt to tame the weapons for themselves, or might seek to destroy them.
I usually run this adventure for fourth-level characters in the D&D 5e system, but I've tried to present it here in a system-agnostic way.
If you need a teaser to send to your group, I recommend using this:
Business is booming in the desert village of Miracle Spring. The Spring is a magic item, a relic of the long-dead draconian race, and tourists come from all across the land to drink of its waters. As adventurers, you've been contracted to keep order in the village. But the ancient draconians left more relics behind than just the Spring. This <insert day here>, some of those relics will surface, and your team will try to thwart a disaster that could rock the Empire.
