In Norse mythology, hrimthurs ("rime giant") is any one of the particular tribe of giants who are made of ice and inhabit a land of eternal cold.
(The story prevalent on the Internet that "Hrimthurs" was the name of the rime giant who built the walls of Asgard with aid of Svadilfari is a misconception, probably stemming from mistaking the tribal attribution of the builder for his name. The name of the actual stonemason is uncertain; it is usually only stated that he was eventually revealed to be a hrimthurs. The translation of "hrimthurs" as "Blast" that these stories usually cite is incorrect: the word is a fusion of (h)rimrime + thursgiant.)
In Norse mythology, Hrimthurs was the person who built the walls around Asgard, the land of the Aesir.
The walls surrounding Asgard were built by Hrimthurs, in return for which he was to receive in payment the hand of Freya in marriage and the sun and the moon.
In order to avoid the payment, Loki lured away Hrimthurs' magic horse, Svadilfari, by transforming himself into a mare and luring the horse away.
