I'm giving you an out

News of Stronghold 109 getting destroyed and taken over by the Experimentals had quickly spread to the rest of human civilization under the Alliance of Strongholds.

If Stronghold 112 and 113 were destroyed by acts of nature, there was nothing that humans could do about it. But for Stronghold 109's destruction, the shadow of a nonhuman species challenging the survival of mankind hung over the incident.

That was because Stronghold 109 was not destroyed by an act of nature. This threat came from a new species that also happened to be extremely aggressive.

The strongholds had been standing in this world for hundreds of years now, while some of the most powerful empires in the history of human civilization only lasted 200 years at most. Therefore, humans had almost become accustomed to the safe lives they knew in the strongholds.

But now, the appearance of the Experimentals was telling humanity they had to reexamine this world.
