You do not carry an shadow of Finality, what you carry is the authority of Finality itself, Time; granting you an incredible boost in power and access to all other authorities. What authorities are these I hear you ask? The answer is all of them. While your actions are restricted to a planetary scale, any action you can imagine within that area is available to you. Furthermore, as you now command all of the Honkai, you can change the nature of it, if you desire for it to no longer makes zombies, it won’t do so anymore, if you want to give every single person on the planet a Herrscher core, then that possibility is also open to you as well.
