|| As any scryer knows, the link between the murderer and the murdered is the murder weapon,|
and a scryer can follow that link from the murdered to the weapon to the murderer.
One rather cold blooded killer thought of a way around this.
By carving blades out of ice, they could kill as they wished and the link would just melt away.
Their killing spree ended when one of the victims got lucky and managed to stab the murderer in the heart with the icey blade.
After being united with the cold heart that created it, the final ice blade has never melted.
