Nananav was a character in Oathbringer who was robbed by Veil and her crew. Veil's crew posed as carpet workers, which allowed them to infiltrate the keep. The name Nananav reminds me of Nalthian naming schemes, with the repetition of consonants, such as Vivenna or Llarimar. I would assume she would be at third heightening or higher, which would allow perfect color recognition, as one line of dialogue from her is requiring the new carpet to be a perfect match of color. Am I reading too much into this?
