In every installment of the series, the Elves are all women with long green hair. They are experts in the field of archery and move quickly to protect their forest. Elves have no relationship with humans despite their geographical proximity. To prevent any adventurer to reach Yggdrasil (although humans can), the elves have designed their forest to get lost easily.
In Valkyrie Profile 2: Silmeria, if Alicia and her team are in contact with an elf, she is returned to the entrance of the Bois. Rufus is a Half - Elf vessel meant as a backup body for Odin to use, in case anything happened to Odin's body. Because of this, Rufus was treated like an animal by the other Elves. When Roussalier - the only elf named the series - comes to help Rufus and Alicia, Rufus feels angry and does not want the pity of an elf. Gradually, Rufus begins to appreciate her help, but Roussalier dies at the hands of the Aesir for helping Alicia and Rufus in their attempt to access Bifrost. It is widely believed that Roussalier was Rufus' mother.
In Valkyrie Profile: Lenneth, a human with great power named Lezard Valeth used Elves for his experiments. This is not the first time they are used as experiments; Dipan had done the same. It is revealed that the Elves are to be vessels of the gods so that they can travel to Midgard. The union of a human with an elf is possible, and Odin comes from this kind of union. Full-blooded Elves are immortal, but Elves who are half-human can gain power, whereas other deities' powers remain the same forever.
Elves are very close to the Aesir.
