He's going to exploit this whole multiverse if he can.  If a few worlds need to burn in the process, Alexei has no qualm with lighting the torch.

One multiverse. Technically Existence is basically an Omniverse, even if it isn't called such that's pretty much what it functions as, so there are multiple multiverses. Potentially infinite maybe? But I don't know how the scaling in that regard works.
