By the way, I had mentioned this to Kindred a couple times in the past. This probably wouldn't be anything that happened too terribly soon but leaning into the FF side of things-

Would anyone want to get involved with Summons? Obviously KH has its own Summons but these would be more personal Summons tied to each individual character, chosen IC, but based on FF summons. So Ifrit, Titan, Bahamut, Ramuh, Odin, Leviathan, Alexander, [url=https://youtu.be/n6AXb2DNE4M?si=CoLE3igFgOIjZ8ta&t=6]Satan[/url]... so on, so forth. 

Could be a more personal 'boss fight' later on in the story for anyone who wants to try and earn the favor of a Summon.

Nobody would be forced to participate or to get a Summon, just an idea.
