I'm getting you (Arn) to a doctor first, so I'll post for Tyrhallan.

I'll leave Eilis for now, since I am planning on slowly bringing in her backstory. 
Eilis's memory fragments will be put in from time to time, this will just happen in little snippets or when the situation calls for it. 
Also since Eilis clearly went beyond her breaking point she'll be blind for a short while and her magic will be shortcircuiting or not working for the time being.
