So after taking some time to talk to everyone around the HQ prior to the final battle (yeah, major spoilers) I noticed Zenoa saying something extremely interesting.
She talks of there being a variable amount of Stars of Destiny in each world of the Infinity. Many of them only have a single star, too. What's more, each different star seems to represent a "destiny" for the world, meaning the ones with only one Star of Destiny were doomed to fall victims to The One King.
As the first Bad Ending you can get suggests, the technique that uses up all of the Stars of Destiny basically destroys all possible destinies for the world, thus The One King still wins and presumably continues on his quest of the Infinity's fusion.
This begs the question: Does this even tie into how Stars of Destiny used to work? In the original world Stars of Destiny are born under their star and are pretty much bound to a fate similar to their Shui Hu Zhuan counterpart. They rally around the Tenkai Star when needed and work together to defeat an insurmountable war.
In Tierkreis, it seems like the Stars of Destiny simply attach themselves onto characters that fit them most. Examples include the correlation between Vaslof and the Tenmou Star, Liu and the Tenki Star, etc. This correlation would be standard Suikoden fare if it wasn't for some people magically becoming Starbearers once they change their mind prior to touching a Chronicle... or some people quite simply becoming Starbearers out of the blue when they're already your allies, like Mubal.
Would this mean Konami is changing the real meaning of being a Star of Destiny? The change of term to Starbearers seemed like a change in localization at first, but it seems more like a change in the fundamental significance of being associated to a Star.
