HM: Michael Enischyo

Honourable mention, @Michael Enischyo

At the moment his story does not play a big role in the Archi Galaxy at all, rather he is his own home galaxy's main character for the Salem Era (which both the name of his home galaxy and the role he plays are unknown at the moment because he is being very secretive).

So currently, he is being used (unknowingly) as a foil to up the stakes for Enoch Archon (the current main character of the Archi Galaxy in the Salem Era).

However, the Law of Equipotentiality (see lore pages within the lore folder "Lore of the Mirror-Universe") allows him the possibility to choose to break out of that role (though he is unaware that is the role he is playing), and become a key figure; because at the moment Michael Enischyo's potential, though Galactic, is not intergalactic.

All that's left is now to see what happens in the future.
