Why Is Fairy Mountain So Special?

Fairy Mountain and the beautiful water feature there, Crystal Spring are very special to Fairies.  I wonder why.  I think it is because both of the fairy clans in Umberland, around Thimblewyck cooperated to keep it special.  All fairies are concerned with nature but each of the two clans are concerned with different aspects of nature.  The two clans are the Li-Su and the Petra clans.  The Li-Su are concerned with plants and animals. The Petra are concerned with rocks, earth and the weather.  Petra stands for rock in another language.  Li-Su stands for life sustaining.  You have heard of fairy gold probably.  Those fairies are of the Petra clan.  Rosequet was a Petra.  Binar and his cousins, Non Ton, Hilda and Marus were all of the Li-Su clan.  The weather is always perfect on Fairy Mountain.  The water is clear.  The plants and trees are beautiful and healthy.  I'm sure both clans cooperated to create it and keep it that way.  Maybe fairies are like bees.  We cooperate in the hive.  I'd better get back to the hive now.  Bye.
