Referred to as "Silence" in the common parlance, the constellation Silentir is historically attributed to Dumat, the Old God of Silence and leader of the ancient Tevinter pantheon. The depiction of the constellation, however, is often debated. Some depict a dragon in flight, while others (also the most common modern depictions) show a man carrying a horn and a wand. Some scholars believe these represented scales, which would point to this constellation being a supplantation of the elven Mythal, but nothing indicates this to be more than speculation.
