Hrimthurs

In Norse mythology, hrímthurs ("rime giant," though commonly translated as "frost giant") is any one of the particular tribe of giants who are made of ice and inhabit Niflheim, a land of eternal cold.

For the origins of the frost giants, see Jotun.

(The story prevalent on the Internet that "Hrímthurs" 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" hrímthurs. The translation of "hrímthurs" as "Blast" that these stories usually cite is incorrect: the word is a fusion of (h)rím "rime" + thurs "giant".)
