Take a look at the Suikoden 1 game map. It's the river separating Senan (Moravia etc.) from Dana (Kirov etc.), and connecting Toran and Dunan. Look at the river, north of Moravia there's a realistic example of 2 rivers joining together, and when the river hits the rocks at the lake banks, it causes rapids. In the end, the water finds its way to the nearby ocean in the northeast (and maybe in the south), after bypassing Shasarazade and several smaller fortifications which protect the capital.
Sounds good, but now I've read the following on Suikox:
A River that starts south of Toran, runs through lake Toran, and feeds into Lake Dunan. This river is considered to be an extremely important trade route between Dunan and Toran.
SARSadmin's Comment: This info comes from the Suikoden Encyclopedia, but looking at official maps, I don't see the river connecting Dunan and Toran. So what's the truth!?"
All of a sudden, a typical example of conflux turns into an unrealistic (at least very very rare) example of river bifurcation, and the rapids don't make sense to me anymore, because a lake can hardly develop water speed which is needed to cause rapids. Moreover, it would mean that Toran is located higher than Dunan, so the stretch between the lake and the ocean must have an extreme gradient (invisible in the game), making the fortifications obsolete (or else, the Dunan river must be below sea level).
To me, the only explanation is that the compilers of the Encyclopedia wrote this close before knocking-off time, you know what I mean. Am I missing something?
