would you ever consider writing a prequel/another book set in this universe? i understand why u had to make the society collapse for narrative reasons but the world u built was so incredibly cool, some of my favorite parts of ur books were just learning ab

Yes, definitely.

In addition to pretty much everything I write taking place in various eras of this same universe, I have a whole series of novellas planned out that take place between Valhalla and Ragnarok that just luxuriate in expanding the world as it exists at the end of Book 1. All V Teams normal adventures for a year.

I very much hope the series gets popular enough to justify writing them and releasing them.
