The long-lived elves are children of the natural world, similar in many superficial ways to fey creatures, yet different as well. Elves value their privacy and traditions, and while they are often slow to make friends, at both the personal and national levels, once an outsider is accepted as a comrade, such alliances can last for generations. Elves have a curious attachment to their surroundings, perhaps as a result of their incredibly long lifespans or some deeper, more mystical reason. Elves who dwell in a region for long find themselves physically adapting to match their surroundings, most noticeably taking on coloration reflecting the local environment. Those elves that spend their lives among the short-lived races, on the other hand, often develop a skewed perception of mortality and become morose, the result of watching wave after wave of companions age and die before their eyes.
Physical Description: Although generally taller than humans, elves possess a graceful, fragile physique that is accentuated by their long, pointed ears. Their eyes are wide and almond-shaped, and filled with large, vibrantly colored pupils. While elven clothing often plays off the beauty of the natural world, those elves that live in cities tend to bedeck themselves in the latest fashion.
Society: Many elves feel a bond with nature and strive to live in harmony with the natural world. Most, however, find manipulating earth and stone to be distasteful, and prefer instead to indulge in the finer arts, with their inborn patience making them particularly suited to wizardry.
The Elves are so steeped in Magic, that throughout their long history never felt the need to develop traditional metalworking arts. Their home islands have little mineral ore and mining it is destructive to the little land they have left. As such the small amount of worked metal used is either imported or worked by magic, and it is rare to see any metallic item of Elvish manufacture that doesn’t bear some enchantment. The exception to this rule is Mithril, a rare metal that only a handful of Elves know the secret of working. It is purchased from the Dwarves as raw ore, and must be worked by hand through secret methods. Instead, most of the typical uses of metal are replaced by expertly worked glass or ceramics, which can be magically enhanced to rival or surpass steel.
Religion: The racial gods of the Elves are dead. The entire pantheon was destroyed during the last great cataclysm, sacrificing themselves to ensure the survival of their mortal children. Since then, most Elves do not worship any gods, and their cities bear no temples or shrines out of respect. A few, mostly younger individuals living among other races, have adopted other gods and even serve them as Clerics or Paladins, but these individuals tend to be viewed with distaste by those who still mourn.
Relations: Elves are prone to dismissing other races, writing them off as rash and impulsive, yet they are excellent judges of character. An elf might not want a dwarf neighbor, but would be the first to acknowledge that dwarf’s skill at smithing. They regard gnomes as strange (and sometimes dangerous) curiosities, and halflings with a measure of pity. Elves are fascinated with humans, as evidenced by the number of half-elves in the world, even if they usually disown such offspring. They regard Orcs and Half-Orcs with distrust and suspicion.
Alignment: Elves are emotional and capricious, yet value kindness and beauty. Most elves are chaotic compassionate.
Adventurers: Many elves embark on adventures out of a desire to explore the world, leaving their secluded island to reclaim forgotten elven magic or search out lost kingdoms established millennia ago by their forefathers. For those raised among humans, the ephemeral and unfettered life of an adventurer holds natural appeal. Elves generally eschew melee because of their frailty, preferring instead to pursue classes such as wizards and rangers.
