Mainverse Taken!Altertale is an AU of the reboot of Taken!Altertale. The events are mostly the same as in the base-AU, but there is a big change in its cast. Since it happens in a different Multiverse, not only the cast changes, but the way Monster species are called also do. While the story is mostly unchanged from the original in the invasion, many differences can be seen after the formation of the reclaiming group.
