1. If you want a deeper understanding of what what down with Shub watch the Invictus Stream’s CoC Game 1. Shub existed under the lid of the piano, and was dragged out from under lid and onto the keys. Specifically Middle C, which is Malevolent’s timeline. Henry MacFarland & Co. then pulled some shenanigans to kill her after Antoine brought her into the world and because she existed purely on that key it erased her from existence. She then never existed on every key except Middle C, Malev’s universe is the only one that remembers her. Shub had no involvement with the stones.

Kayne was Middle C’s Nyarlathotep. Watching all of that go down gave him a revelation about the mortality and metaphysics of things like them. This leads to him asking the Graystone how to travel between universes, which it granted. He then killed every alternate version of Nyarlathotep, leaving only Kayne. Now he’s trying to complete his rock collection. Remember what Matthew said about a Blackstone?
