Sorry, I've been distracted by the background stuff...
I don't see Thorn having much to add on any of what's gone on so far. She's not knowledgeable in magic, and nothing we've found seems to tie into Munsu or the assassination plot directly...though it might explain why Thomas betrayed us, if his reward was eternal 'life.'
I don't mind noncombat stuff, and I enjoy mysteries...it's been fun reading it. This particular mystery just happens to be one my character can't add much to. Which is fine. There'll be other times when my abilities are in the spotlight. It's all good.
