Hrimthurs

Hrimthursar, or frost giants, are ice Jotunn who hail from Jotunheim. The valkyrie Sarah Irine is able to summon them at will. Thus far, they've appeared on two occasions: when Sarah was fighting Fenris Fenrir at Breidablik and when Sarah attacked her former home of Payon. They were defeated by Fenris and Lord Irine respectively.

In Ragnarok Online, Hrimthurs is referred to as Gigan and Gigantes.
