Riddle me tender

Though I may speak in riddles, it tends to tell a tale One like no other, once captured under the spell What lurks in the shadows, there's lasting discontent And there upon the gallows, where many lives were spent Lies a truth within the walls, life within the trees Valley of death arrives, alone at ones bare feet The crow trusts no one, as the fox he is sly The creeper of the moon, the Apple of my eye
