For my DnD players in our Friday Game, if you are reading this please, move along.
Last November, my Friday players hit 20th Level. I wasn't ready for an Epic game, as I hadn't worked it all out yet, so we started playtesting a dungeon that we should be finished with before it releases in September. And I think I've got the foundations in place for a epic battle amongst the Multiverse.
Long has Orcus, Demon Prince of Undeath lusted after the Raven Queen's divinity presiding over Death, Fate, and Winter. For centuries he has plotted against her, his corpulence rippling like bitter storm stirring a toxic lake in his quest to usurp her. He has tasted merely a drop of her powers, centuries ago, as he began to probe the young goddess, after she had conspired against Nerull.
In that exchange, Orcus offered the Raven Queen a weapon of the purest darkness, Black Razor. His price was, ostensibly for the his old ally, the Queen of Chaos and it was for Miska the Wolf-Spider's prison to be moved from the Shadowfell's Demiplane of Dread and Desire, which was created to house the Wolf-Spider, to be moved to the Abyss. The Raven Queen, vastly underestimating the Prince of Undeath, did not realize that their pact would give that portion of the Demiplane of Dread and Desire to the Demon Lord and transfer it to Pandemonium. Yes, the Raven Queen had Black Razor, but a portion of her power had been eternally lost to Orcus, infuriating her.
However, the Raven Queen has been watching what has been occurring within the Abyss, as several Demon Lords have escaped to the Prime Material Plane of Faerún, including Orcus, the death of Tiamat at the hands of a Cabal of chromatic dragons, and the disappearance of Lolth. It has lead her to reach out to the Queen of Chaos to solicit support, believing that they might find common ground in their enmity of Orcus.
For her part, the Raven Queen still claims to have some hold over the portion of the Demiplane of Dread and Desire that holds the Queen of Chaos' lover and general, Miska the Wolf-Spider in Pandemonium. And the Queen of Chaos, for her part, has claimed that she can enchant Black Razor to slay Orcus, once and for all. Of course, all that she requires is the freedom of her beloved and the opportunity to rule the Abyss, for the Raven Queen to walk away after the Prince of Undeath is slain.
All that either Queen requires now are heroes, valiant or foolish enough to go after Orcus and slay him. Although, for her part, the Raven Queen has much to offer her champions. Saint Cuthbert has been trapped within the Demiplane of Dread and Desire and she can offer his freedom in exchange for their service. Additionally, the Raven Queen is older and wiser now and she is prepared to use Miska as a bargaining chip. Now all she has to do is lure her champions into their service, with Death, Undeath, Fate, and Winter all hanging in the balance.
