That theory from Daily dose of cats yesterday gave me my own idea for a theory on why men aren't in the magic realm, or rather, why we find none in the places we can visit.
I will fork off of Ddoc's theory with the gendered segregation, however I think that instead of the men and women going to war, the men were all brought over to the Elves. We already saw that Elena is desperate to bring over any and all magic folk she can to the world of machinery, and from the little lore sprinkled throughout the games dialogue, you find out that basically all Elves are like that. And I believe that they began with the men of magic because they are way easier to bring over. What did they use for that? Idk maybe Elfkind invented Legos or something.
So what I'm saying is that the men aren't gone, and neither are they dead. They're just in the one place that was promised to them as eternal heaven which is the same place that has been entirely unaccessible to us.
But that's just a theory. A MAEVE THEORY! Thanks for reading.
