After some years being the Arch Mage, Blisterworts needs a holiday. A long holiday. She's turning 26 in this picture and have done great things.
The meaning behind the quote: A hero shapes the world by the choices he makes, both good and bad and as he turns into a legend, there are those who misapply his name. "The world will speak for him" in a way means to me that some people will use the legend to support their ideologies, for better and worse. (think Jesus and Talos, the best examples I can come up with)
