Norse Mythology is a specific kind of mythology introduced in Grand Theft Auto: Vice City, particularly on the radio.
Norse Mythology is largely based on Old Norse paganism, dating back from ancient times. Norse mythology believes in the Norse Gods. The Norse gods are divided into 2 groups, the Aesir and Vanir, plus the giants, who came first. Some believe the Vanir gods represent an older pantheon of the indigenous people, who were encountered by the invading Indo-Europeans. In the end, the Aesir, the newcomers, overcame and assimilated the Vanir.
