Cold One Chariots

Cold One Chariots are sometimes given as gifts to those rare knights who have pleased Lord Malekith with their devotion and prowess in battle. To possess such a machine is a symbol of great prestige, and is ranked amongst the highest stations in battle, even though the Cold Ones' truculent nature can often bring the chariot to a jarring halt at the most inopportune moments.1a

Should the crew retain mastery of their chariot, they thunder across the battlefield like gods of war, wicked spears leveled and Cold Ones roaring fit to freeze the blood. In the last moment before impact, the crew goad their steeds to one last effort and the chariot crashed into the enemy ranks, crushing foes with the weight of its impact and opening flesh to the bone with the blades upon its flanks.1a
