Mourning runes are Marks worn by Shadowhunters to honor a dead loved one. They denote grief, sorrow, and mourning. They are purely symbolic and do nothing to ease suffering. Some of these mourning runes may be permanent.
Though the color for mourning among Shadowhunters is white, the mourning runes are red. They can also be drawn in silver on objects such as dresses.
One known mourning rune is the Remembrance rune.
