Death imagery

Introduction
Death imagery is a piece of phenomena found only in White Rose within the Nymphilli species. Death imagery is a passive effect created by the death of a soul, it's similar to the process of how a Soul Stone is created where the user outputs their last bit of magical energy. But instead of resulting in a stone that allows someone to use your type of magic, it imprints what the soul last saw and thought of moments before death, allowing the wearer to see what the dead thought of and saw in their last moments.

Documented uses of Death imagery
1356: (the first documented case of Death imagery) a brother wore the mask of his recently deceased brother and was reported to be washed over with feelings of happiness and visions of his family when others wore the mask they reported the exact same feeling.

1358: after the same brother revisited the mask and found the exact same effects he went to the newspaper with his finding and the story went viral. A day later a Nymphilli was murdered and police were able to use Death imagery to track down the killer.
