The King in Yellow
2020
The forbidden play, The King in Yellow, has driven folk to madness and destruction. Naturally, some of you want in on it.
Inspired by the works of Ambrose Bierce, Robert E. Chambers, and H.P. Lovecraft, this warlock patron also comes complete with two new Eldritch Invocations and a new artifact, the eponymous play itself.
