Yanaril is an Altmer Thalmor agent found in Woodhearth.
Before losing Aranias' memories, the Wilderqueen told me that she knew about the Veiled Heritance plot to steal the Staff of Magnus. She suggested I go to the city of Woodhearth.
After the death of Prince Naemon, Vicereeve Pelidil assumed leadership of the Veiled Heritance and stole the Staff of Magnus. Razum-dar has tracked him to somewhere in the area of Woodhearth.
