my theory is that all of the original monsters from the first dungeon were transmigrators and they've been trying to get home forever for various reasons. the only beings who we know have gotten the call are transmigrators so far and im not sure if they've confirmed if any non transmigrators have recieved it but the three confirmed monsters to receive the call were. i wonder if we will learn that the ancients were humans or even members of other worlds?
