I ADORE drakonis. I go there for all my character avatars.
I've actually looked for pictures there that look like her. I thought I'd been through all of them, but I don't think I ever saw that one. Which section was it in? It's definitely the closest I can think of, but still not quite there. The Iron Queen is more stoic, tends to keep her hair back/up and is more straw-blonde. (Yeah fat chance of me ever finding a pic that meets my specifications, but whatever.) But that's definitely the closest I've seen. The queen would seem pretty if she wasn't so cold.
Closest real-life approximation I can think of, is think of an older-looking Charlize Theron who never smiles and wears her hair back all the time.
That gives me an idea to start a "known-NPC" thread, with a little pic (if I can find one that fits) and description of important NPCs the party(ies) have met so far.
