I'm running multiple d&d games for both friends and family. My friends are currently playing The Curse of Strahd and loving it but it's just by the book.
My family just finished The Wild Beyond the Witchlight, which I had heavily modified and plan to release a boom detailing what I did and how it went. After that this group returns to my homebrew game, so...
I need to revive a third game, also with friends, which is their heroes in the same homebrew world as I plan to bring the two groups together for a level 20 finale.
They are, vaguely. The situation is that two worlds from parallel timelines almost collided and we're sealed into a bubble plane to keep the catastrophe contained.
One party from each world is unraveling the how and why. At the center is a pair of liches - the same individual from each world - whose phylacteries are each other. If you dint defeat them both in the alloted time, the other lich rises again.
None of the players know about the liches yet, but they do know their name, Zeitounessian.
