Ah, Emrys. What didn't he do? I'll try to stick to things that I'm sure are known or at least highly suspected. These all relate to his efforts to try and rescue Tertia after she Fell.
He tricked students into helping him rip the heart out of a friendly Aetherial.
It is strongly suspected that he lowered the wards on the room where the school stores dangerous artifacts and took one out that then fell into the hands of a Fallen.
From this point, I'm not positive what was known to PCs and so can't comment. If any PCs care to chime in with things that were known, please feel free. For that matter, if staff members know anything further that the PCs knew, also feel free.
