Setting
As mentioned above, the game is set during the Gathering Storm event. To summarize: The armless crybaby known as Abaddon the Despoiler launched his 13th Black Crusade which ended with him rage quitting and dropping a Blackstone Fortress upon the planet of Cadia, destroying the planet (though it broke before the guard did) and it's pylons resulting in a chain reaction of warp-storms that created the Great Rift and divided the galaxy in half.
During this time, Ynnead awakened (thanks to the machinations of a certain Dick) and chose the craftworlder-turned-corsair-turned-wych Yvraine as its emissary. Yvraine saved the survivors from Cadia's destruction and travelled to the Ultramarine's homeworld of macragge where they woke up Roboute Guilliman from his ten millenia long coma.
