Aha, okay :). Nice that I gived some ideas. Anycase few facts of basic fantasy elf;
-They can live up centuries but they dont never make wrinkles
-They have pointed ears (and add from Elven Maids vs Barbarians game which is still on site, or just as generall 'adult' idea about them) and the ear tips are sexually sensitive spot
-(from Elven Maiden vs Barbarian) the elven women have two hymens and it is tabboo for breaking both in elven society. Most women who break both are considered outcasts.
-Elves are naturally tied to wonders of nature and magic. So shortly said tree hugging wannabe mages naturalist attitude
. So many elves like to be outdoors and often have magicall abilities or spells.
-Elven women are slender and less curvier than most human females (but many break the rule description and give them large breasts which look larger when consider their generall body frame. So it does not matter really).
-Most generic devotion most elves are good or neutral in world view, some can be surprising cruel to treecutters or those who have killed elves.
-Elves hair and eye color are common colors found in the forests. Like hair can be green while eyes can be dark red like rose petals.
-Both female and male elves dont possess pubic hair besides their eye brows and hair.
Then the details vary what fantasy world we are using or what variant of elf. Examply drow have alot different details from generic elf besides looks (they are ebony skinned elves whit white hair and have red, purple or topaz colored eyes). Anycase I hope this helps understand the elves at surface wise but there are alot of details regarding their psykology.
-Elves tend focus on long term goals, it's naturall when consider that invidual lives centuries. So examply they dont make or buy things which are used completely in less than a day if that is not item's purpose.
-Elves dont like things which are ugly, non-gracefull or brutish, destructive or evil in behavior. Orcs (think Lord of the Rings orcs) fit to this description so they naturally dislike/hate them.
-Elves are often sexually free spirited among their own kind but they are less 'free spirited' among other races. It is well known fact that human and elf union makes half-elves which dont belong to neither world and elves view it as waste of life (altough they are fascinated about them and humans and some elves take human lovers because they bring out 'fresh wind' to daily relationships often but watch out for pregnancy).
-By defination elves dislike any unnaturall things like necromancy, undead, mutantic beings or something which corrupts and changes. Elves like changes but not those which cause harm to anything living being (and they consider trees and plants as living beings and so also animals).
-Elves can be slow in change in lifestyle wise but elves are sometimes unpredictable in personality and behavior.
And it gets more complicated after those things, but I hope this gives idea how elves behave. Also good way to learn something about them is to observe games which have elves. But in truth elves can be unic in personality and behavior and many break many 'standard' rulings of generic fantasy elves. So good mix for standard player controlled elf is 'bit standard, bit twisted standards and rest own mix'. So, there can be elves who love plants and trees more than standard elf but despises any magic which tries transmute or change trees or animals (including fellow elves using the spells) but sexually they are very active and take any partners as they wish (even going so far as taking orc lovers to shock other elves).
