I toured Sslanis and Kion for the first time in a very long while and noticed the stream crossing north of Sslanis. It's impressive to say the least.
Feladan seems like it was meant to have streams and waterfalls on a much larger scale. Between Forest Guard and South Gate, there is a lowpoint running out of the mounts, across the road and continously down hill (minus one short hill) to the east of Feladan. On that side of the city there is a large empty valley that has one small strip of land protecting it from the sea. There are additional valleys/channels crossing Feladan as well (though the white grape vines might need to be moved from one valley and the migration of the deer checked). Another channel runs from out of the north from the Harton Valley(?) mountains. The terrain itslef is well done, it could just use the same beauty that Parsinia has seen with it's stream.
