Anna checks over the items, noting no magical auras present nearby. Looking over the shield she doesn't recognise the heraldry. It seems almost Hyperborean in design, but even then shows signs of unusual craftsmanship perhaps predating even that ancient empire.
She similarly scans the room that was broken into, again finding no sign of magic nearby although a faint hint of unknown magic beyond the room to the north-west and a stronger (moderate) hint of more magic behind the walls to the north.
Spoiler: Anna check to ID magic auras

Elissa meanwhile checks the door near Bjorn (AK41), finding it firmly locked.
