Abydon was one of the gods created by the Engwithans, devoted to duty, preservation, progress, and industry. Although the gods decided to not interfere with the progress of kith civilization, his peers recognized the need to eliminate the Engwithans as a matter of self-preservation. Devoted to a fault, Abydon opposed Ondra's plan to destroy them by pulling Ionni Brathr, Eora's smallest moon, down from its orbit. Abydon forged a special hammer in the White Forge, located in what would eventually become the White March. Channeling all his strength, he threw the hammer against the moon, shattering it and causing most of the fragments to land harmlessly in the ocean. However, the biggest shard remained on course. Abydon, for want of a better option, threw himself in its way, protecting the Engwithans. The moon fragment hit him square in the face, pulverizing it. His corpse fell in the remote mountains of the White March.
The ever-sorrowful Ondra decided to honor his memory by erecting the Abbey of the Fallen Moon around his body, hiding it in plain sight. She also erased the memories related to his death, for if he remembered, it could shatter the fragile peace between the gods. She adopted his tools, the Eyeless, as her own, and swore off all contact with the god of smithing to maintain the secret. Abydon's soul returned in time, and he continued his labor using a new body of metal he forged for himself. However, the losses sustained due to the moon's impact were severe. He lost his will to preserve as well as the memories of his demise. The Eyeless remained, each with a shard of their maker's soul; able to restore the things he had lost, but prevented from doing so by Ondra's machinations.
