Selias Jodame
Selias Jodame was a Sage who wrote a history of Shadow Valley before it shifted in time and space. He was tasked with surveying what happened there by his "masters" after he finished his studies in Emer, most likely in the early 6000s Second Era, before the founding of Quellburn or possibly at the very beginning of the Wars of Dominion. Whether he was a Loremaster or Scribe of Nomikos is not inherently clear, because the word "Sage" was used in both contexts, and they both had councils who assigned these kinds of missions in I.C.E. Age GemStone III.
The modernized form of the story labels him as a "Master of Lore" and Advisor to the Council of Biblia, but very little is known about him specifically.
Selias was familiar with northern Jaiman from his youth, and was surprised to hear what had happened to Silver Valley. His story recalls a young human named Jaron Galarn who acted as a tour guide for the wild horses of the valley, and his investigation pieced together tavern tales that largely account for what happened. The valley was exploited by miners who inadvertently awakened a powerful extra-planar entity that was dormant deep underground. This was necessarily before Lorgalis conquered the region in 6521 Second Era, who might have been the implicit villain of the story.
