The Astronomicon keeps the daemons at bay, and also makes it easier to travel in the warp considering the Chaos gods current influence. If it fails, humanity will have to find a different way to get around, and will very likely split into hundreds of thousands of factions. I am more interested to see what the Space Marines would do if the Emperor dies.
