When Malekith obliterated the northern citadel of Har Kaldra, he offered neither warning nor quarter. The iron-clad fortress was blasted to rime-scarred splinters with a single cataclysmic spell. Ever after, the freezing north wind has wailed with the agonised voices of those who perished that day, and its chill grasp can be held at bay by neither fur nor flame. It was from scattered shards of Har Kaldra that the Chillblade was forged. Its merest touch freezes not only the physical body, but also the soul within, leaving the victim paralysed and easy prey for his attacker's next strike.[1a][2a]
