The Vanir god Freyr is called the Lord of Alfheim; it is said that the patronship of Alfheim was given to him as a tooth-gift. For the most part, this is a ceremonial function, but it is Frey who speaks for them in the Aesir's council, and they need him on their side. That is not the only reason that he is treated with a great deal of respect; the Alfar revere his affinity for fertility magic and plants, although they are uncomfortable with his yearly sacrifice and death. His wife Gerda is not so well liked, being an etin-bride, and was almost cursed by the Alfar in the beginning of their marriage.
