Not much is really known about Niim. She's quite mysterious, a legend in some parts. It is said that she lives by a waterfall running through a forest ontop of a mountain. A river runs down it, and several small streams are connected. That is her way to travel, and although it's much easier for her to travel down than up, she can swim against the river quite well. Many of the creatures of the forest are indebted to her. She has saved their young from death in the waterfall, or in the river.
