Coast Scire, the 4th most populous, much smaller than the big three but about twice that of the next 4. Home to neither the start nor end of the Lucin River, the river cuts right through the center, and most of its population lies on its banks.
It's capital and largest city, Perscon, lies near the start of It's section of the river, and is split in three by a tributary, 4 largish cities can be found going down the river but none nearly as large. Surprisingly, Coast Scire has no towns on the mainland, it's only two are found on its two small islands, and the 5 cities in its mainland are all on the Lucin River.
It has a relatively smooth coast, very long, but not the longest, and a few small islands, 2 big enough to be on the map, to be exact.
