Keys to the Circles (Eberron)
Welcome to Eberron!
This is my first campaign as DM. It is a journey set in Eberron, following an unexpected group of companions. While first agreeing to investigate an abandoned temple of the Sovereign Host, the group eventually find themselves being led from adventure to adventure by a host of both colourful, charismatic and deceptive characters.
After that, take a look at your wiki. There is some more helpful info there.
