Opening the silver scrollcase, you find another fine painting - a much more delicate work than the others. It is marked with a silver insignia in a corner: “Daharil Millicent Maral Auvryndar” next to the title “Fireside”. (click image to download and save)
Could it be? That guildmistress Millicent Maral is actually the artist you’ve been looking for this whole time? You suspect by the insignia, the Drow title she didn’t use until later in life, that this is a much later work.
You roll the artwork and return it to the case.
