ithil: shining white moon

"Because the Elves that first came to Valinor especially loved Telperion, Yavanna made a second tree like it to stand in the city of Tirion where the Vanyar and Noldor dwelt together at first. This tree, named Galathilion, was identical to Telperion except that it gave no light of its own being. It had many seedlings, one of which was named Celeborn, and planted on the isle of Tol Eressëa.
In the Second Age, a seedling of Celeborn was brought as a gift to the Númenóreans, that was known as Nimloth, the White Tree of Númenor. It lasted through the vast majority of the realm's duration, but when Sauron took control of the island he had king Ar-Pharazôn chop it down.
Fortunately Isildur managed to save a single fruit of that tree. Of this fruit later came the White Tree(s) of Gondor."
