History

Lyria's Myth The Aetherscribe Quill was once the instrument of the renowned Nephilim bard, Lyria the Melodious, who lived in the city of what is now Alderland and strolled accross the land of the north long before it became known as Eldonia. Lyria, having a foot in both angelic and mortal realms, possessed a unique blend of divine and arcane magic. Using the quill, she transcribed the very fabric of the universe into verses, creating enchanting music that bridged worlds.
