Domains: Knowledge, memory, learning.
Era of ascension: Golden Age of Man (~130,000 years ago). Cohort: dead. Died: God War & Long Winter (~75,000 years ago), when the Long Winter's fires — both from the Kajiit eruption and the subsequent chaos — burned the great libraries that formed the physical center of her worship.
Worshipped by: Scholars, scribes, archivists, and teachers across the Golden Age civilizations. No living culture maintains her worship, though some scholarly traditions invoke a vague "mother of libraries" without knowing her name. (The worships edge is authored downstream on the worshipper, not here.)
Graelith's death is the reason so little is known about the Golden Age. She governed the preservation of knowledge, and when her following broke, the institutionalized effort to preserve records broke with it. What survived the Long Winter survived by accident; what Graelith's temples had protected was lost with her. The lost ages are, in part, her legacy.
