Now that Mathius isn't being disturbed by people castin spells outside his door, he settles down with his chosen book on Mentem. He has been studying it for a few hours when he takes a break for refreshment. As he walks around the workshop his gaze falls upon the door to the interior and the armour within.
He stops suddenly - he remembers something important. He dashes into the room, and there sits a sealed chest covered with house Verditius markings. He cries aloud "How could I have forgotten such a treasure? What must my predecessor think of me?" He tries to pull the chest forward into the light more, and starts to examine the markings on it in detail.
(Assuming that he can't work out a way to open it from his examination, he will attempt some spont InHe spells to determine how to open it.)
