Twin childs to their parents Grotheim, Silkolf, and Toma, Heima and Heimsil are often seen in each other's company. With their green hair, bright blue eyes and sinewy bodys they both look just like their grandfather (say those who have known him). To help others distinguish between them, Heima and Heimsil each wear a necklace with their name, and their parents claim that they never even attempted to exchange them and see who would notice. The twins are amiable and charming. Between them and around close friends, they betray a wicked sense of humour, but never behave in mean ways. They are well liked.
