@Totallynotalizardspy A fitting name. As for the origin story, make him the last of the ancient Hyperboreans. A relic of the Golden Age of a civilisation that spanned the globe where people lived up to a thousand years in complete happiness. A civilisation where and spirituality, culture and artistic achievement flourished and a time of miracles. Before a great cataclysm tore it asunder.
Now he wanders alone in a world he no long recognises. A man of faith operating in a desolate spiritual landscape working unceasingly to bring hope, strength and the wisdom of his peers to those in need of it.
