A Thundertusk was once housed in the Imperial Zoo as part of the Emperor's famous menagerie. During the first few months of captivity in summer, the Thundertusk was docile and sickly, not moving at all. When the howling winds of winter came, however, the beast roared to life, freezing its enclosure with thick ice, before shattering the walls with its mighty tusks. Enraged, the Thundertusk rampaged through the city. It was last seen heading northwards.
