I'd say about 16-17 if only because of the amount of people complaining about her non Shiva dress outfits in E8 and E8S. I don't like how she looks younger though look at F'lhaminn who is supposed to be much older than she appears to be. Part of me wants to believe that she looks younger due to her not having life experiences until Thancred broke her out of jail. I mean heck I'm older than I look and people assume I'm at least eight years younger until I tell them my age. We also know that SE has an issue of giving npcs faces that give us a better visual clue as to how old someone is. Koji and the rest of the Lore team are just going to have to put out another book. >.> <.<
