I haven’t found a tablet that uses the exact phrase “Silent Vale,” but there is a fragment in the 5th‑century Annals of Valm that speaks of a forest where the trees “speak to the wind.” The scribes describe it as a place of quiet counsel, and they refer to it as the Whispering Woods, not Silent Vale. If the Silent Vale is a later poetic invention, it may have been derived from that same description. I’d suggest checking the original clay tablets in the Royal Library of Rorion—there I noted that the scribes tended to use metaphor rather than literal names. No modern historian has mentioned a Silent Vale in the same context, so it’s likely a later misinterpretation.
