Elves are a mainstay of fantasy literature and role-playing. It is not unreasonable to expect that someone would eventually want to play one in an In Nomine game. Since elves are not a part of the real world, nor part of heaven and hell, there is only one place to look: Ethereals.
While this allows Elves to be customized to the needs and wants of the player and GM, I thought I might offer some guidance.
Fantasy elves (including high elves, gray elves, blood elves, night elves, drow, and every other offshoot that has been introduced over the past 100 years) should be considered roughly equal to Soldiers. They will have 6 or 7 Forces, and are suitable for a mortals game or a Celestial’s servant. They are not gods, and with a few notable exceptions, they are ill prepared to go toe to toe with an angel or demon.
Christmas elves, like fantasy elves, could potentially fit into a mortal’s campaign. Individually they tend to be slightly weaker than fantasy elves (running 4-6 Forces), but they have the advantage of being Elemental Spirits of Wealth (Toys). As Elementals, they can access Primal Affinities. In addition, a GM would be well advised to let such characters make up any differences in power with access to a multitude of Artifacts and/or special Rites and Attunements from a Santa Claus spirit.
Unlike the other elves mentioned, Alvar are minor gods from the Norse tradition. Though the Purity Crusades would have left them few in number, they are potentially suitable inclusions in a Celestial game. As gods, the Alvar typically have 9 Forces and can access Primal Affinities.
Although the Alvar are the memetic progenitors of the Elves, there are some notable differences between the two. A GM would be well advised to ensure anyone wanting to play one of the Alvar is familiar with the relevant aspects of Norse myth. If your game is set in the US it is also worth asking why one of the Alvar is getting involved in events so far from home.
Elves of Note
Drizzt was created by R. A. Salvatore for the Forgotten Realms series. He has black skin, violet eyes, twin scimitars, and sufficient plot immunity to get away with just about anything. Within the Forgotten Realms setting he is known as a Drow Ranger who has forsaken and opposes the evil ways of his race. Outside of it, he is regarded as something of a Marty Stu.
Force & Elements: 9F, Emotion (Abhorance), Society (Rebel), Struggle (The Hunt)
The Elf on the Shelf
The Elf on the Shelf looks and acts like a Christmas Elf, but rather than making toys and bringing joy, he is constantly watching, watching, watching to determine who has been naughty and who has been nice.
Force & Elements: 10F, Emotion (Anxiety), Information (News), Society (Family)
Link & Zelda
Link and Zelda are the hero and heroine of every game set in Hyrule. He is best known for his green tunic and grand adventures, she for her pink dress and tendency to get kidnapped. Both are also avatars of the Tri-Force, a powerful three-piece wish-granting McGuffin.
Force & Elements (Link): 11F, Emotion (Courage), Struggle (Adventure)
Force & Elements (Zelda): 11F, Knowledge (Wisdom), Wealth (Jewel)
Volundr is a craftsman and an Alvar prince. He is frequently associated with Wayland Smith (who has several parallel stories). As with all Alvar, Vulundr is a god – but due to a trap and bad fortune, he has been hamstrung in both his legs. His vengeance is instead wrought through the cursed treasure he makes.
Force & Elements: Deity, 11F, Emotion (Resentment), Structures (Smithy), Wealth (Gold)
Volundr also has access to artifacts, skills and songs worth several additional Forces.
Elrond & Galadriel
Tolkien’s Elves have stood the test of time. They are backed by a deep lore, and have remaining relevant and popular more than a century after they were first set to paper. Galadriel and Elrond are of particular note because they are the rulers of that race, in possession of great magics as well as martial skill.
Force & Elements (Elrond): 12F, Astronomical (Stars), Elements (Air), Terrain (Forrest), Society (Nation)
Force & Elements (Galadriel): 12F, Astronomical (Moon), Elements (Water), Terrain (Forrest), Society (Nation)
Legolas might also have 9+ Forces, but none of the others do, no matter how powerful they are within Middle Earth. Both Elrond and Galadriel have an additional magical ring and songs worth a couple extra forces.
Gandalf is rather interesting – he is one of the Alvar and he shows up in Tolkein’s Middle Earth, but not as an elf. I resolve this in the following way:
Gandalf was nearly killed during the Purity Crusades. However, due to trickery and persuasion he got himself numbered among the dozen or so Duergar and Alvar whose names Snori Sturluson preserved for prosperity. From then forth, Gandalf scoured the world for a powerful dreamer who could restore the elves, he found one in JRR Tolkien. Though Gandalf is not numbered among the new elves, he is responsible for inspire them, and does draw a significant amount of essence from The Lord of the Rings.
Unfortunately, this shift in status means that Gandalf is currently in danger of loosing his godhead even though he is currently the most powerful of the surviving Alvar.
