Well wtf is Telperion?

Well fuck you.

Telperion is the eldest of the two trees of Valinor. Telperion had leaves dark green on top and shining silver below. The stars of Varda was made from the dew that dripped from his limbs, and the moon from his last flower.

Telperion perished, along with Laurelin, in the Darkening of Valinor, an event just before the first age in which Melkor and Ungoliant reeked havok in the land of the Valor. After the trees were destroyed, Yavanna made an image of Telperion called Galathilion.

You may be familar with one (two if you've read the books) of Galathilion's decendents, the White Tree of Minith Tirith.

That's about all you need to know about Telperion.
