Legend
It’s implied to be an equal partnership, Miska will also be remaking the multiverse.I realize that is the story of the book, but that doesn't work for me. IMO, even though, or possible because, Vecna did the work Kas can't usurp it. He doesn't have the strength to handle that power.
Also, why would Miska help Kas remake the multiverse?
Another big reason Miska would be helping Kas is because Kas offered him his freedom.
