The defenceless nymphs are easily caught by the Tealcats, but the lucky ones hide amongst the Suntrees and take shelter within ponds and water. The nymphs do not need to breathe, but they do need mana. The nymphs living among the Suntree forests grow weak die from lack of mana, as the forests are too warm for Icefluff. The nymphs who come to live within the waters grow strong and smart, from the mana upstream. The wiser nymphs try teaching newborns the awesomeness of mana, and after many cycles of death and birth, the nymphs gain an affinity for sensing mana, because it is like food to them. One day a herd of Snowstubs come to drink from the nymphs' home, and the curious newborns frolic with them all day. When it comes time for the Snowstubs to leave, some nymphs join them out of playfulness. Playfulness becomes curiosity, and curiosity becomes fear. The mana emitted from the Snowstub wool is quickly left behind on their migration, and most of the traveling nymphs perish... The Saerics find the survivors and try to tame them, but their first attempts fail due to lack of mana. When the Saerics try to eat the dying nymphs they realize that they are made of mana, and thus inedible. A revelation is made, and a few of the nymphs are kept as pets. What the wiser Saerics and water nymphs discovered, is that ♥water nymphs♥ need ♣Icefluff♣ to survive.
tl;dr - Water nymphs live near Icefluff.
