What is Yuber, and why is Pesmerga chasing him? What are those two up to?
If I recall, Yuber is simply an human embodiment of Chaos (more specifically, War and Conflict rather than just "random".) and Pesmerga is his opposite counterpart.
Given Yuber's nature, they would probably show up again if Konami had any plans on doing another game in the actual Suikoden universe rather than...well, whatever they did for the DS game (I haven't played it, but it features Porpoise People..)
Personally, I'm more interested in a story about the Circle Rune and Harmonia's High Priest Hikusaak, since they seem to have some relations to the other major plots (especially 3, and parts of 2. Remember, Harmonia gave Highland the Beast Rune).
I'd be perfectly willing to endure shitty religious symbolism for it even!
