The Grey Moonstone

The fabled of all the stones. The stone that powers the realm of She'Ol. The one stone that is keeping its denizens here. Dubbed, The Death Stone, its power created this realm and is tied to it. The other stones came from it as the source. The source stone is the obstacle keeping its denizens from returning to their home. It has a guardian as the others do. This guardian is most tragic story of them all. It has been affecting the guardian since their arrival here but they do not realize it. As with all the stones, Its gift of immortality bears a cost, the mind. The mind is such a fragile thing, even if the body continues on, it will eventually give out. The last trial is ahead. Defeat the guardian of the Death Stone and freedom awaits.

The Death Stone was utilized by Britanus nicknamed MUD. Its power flowed through him granting him extraordinary abilities of unrelentless endurance and practical invulnerability. In the end, it took the entire party to defeat MUD and free themselves. However, that was not the only consequence. As it appears, the final stone was a crystal deep within the Depths of She'Ol and its power held a certain Lady Death prisoner. With the final warden defeated, She was free to roam the multiverse once again. As a reward, each of the party members were given the ability to return back home. With its power depleted, the realm would soon fall to chaos but this was no consequence as Lady Death was now free from its chains. The consequences of this decision will ripple throughout history.
