No predetermined identities. The only predetermined factors are that this is set in the past, and Ken and Arsen, for obvious reasons seeing as they're established as existing in the modern day, can't die, and thus I'm playing them as NPCs. Also established, I guess, is that they are in Halcyon City, and because they're attached to Ken and Arsen, are automatically connected to the Guardians (though, as with our main cast, the exact degree to which they're attached is totally up to the individual player).
