All was silent in the grey darkness of the mists; the distant sound of a gently strumming mandolin came to him, and he heard the clear sweet voice of a woman singing a wordless song. Entranced, Ailwon followed it forward. Slowly, the mists separated, and before the elf loomed a monstrous tree, that seemed to stare down at him with great dead eyes. Enchanted by the voice, Ailwon approached the mouth-like cavern a the base of the tree. His sword grew heavy and fell from his hands.
