yo another theory real quick, what if Mythshore was killed by our teacher? like he went to Northcrest so what if his intention was to join up with the people who were going to kill Mythshore/attempt whatever happened there? and he like escaped or didn't and later we can find his remains or some proof he was there?
forgot entirely about some things so ignore the dead teacher idea, i HIGHLY doubt thats a possibility now. still think its possible he was involved in it tho
