The Elf Wars

The story of a great war between Elven kingdoms. 
Long, long ago there were three elf kings: Galthizar, Celizar, and Azarel, and they waged war nigh the eruption of Volinor. Now of the three Galthizar was the most cunning, and he was a dark elf. Celizar lived to the south in the Great Stalk and his kingdom was most populous. Azarel ruled the High Kingdom of Avalon and had the most friends, the strongest armies, and the deepest magic. Galthizar being of dark brood, reigned in that very mountain of Volinor, and he had in the depths of his mountain an amber disk, which he used to spy on the other kings.
