These are classic "legendary" sagas, with everything from a dragon to some hideous giants to plenty of crazed berserks and wicked enchanters. At the same time, these sagas are set just a couple of generations before the settlement of Iceland, and the heroes are said to be ancestors of prominent Icelandic families. . . so these are the kinds of stories that Icelanders once told about their origins, and they may have a dimly remembered, almost obscured historical core.
