Elves practice a sort of democratic chaotic feudalism. Each elf pledges fealty to a liege lord. Males and females may take any role in their society.
Either party is free to withdraw their oath, but they must meet face to face in the presence of a neutral witness (not sworn to either party) and speak the ritual words to unbind themselves legally.
An elf who has no liege lord is a King, and has a vote in the Council of Kings weighted by the number of vassals he or she ultimately commands (i.e. the king's vassals' vassals, and their vassals in turn, are counted).
Some elves are complete independents and are kingdoms unto themselves. Husbands and wives need not be vassals of the same liege, though normally they are.
Elves tend to be sequentially monogamous. They marry, they divorce, they remarry. If there are any children, they generally wait until the children have reached the age of majority (around 101, for elves), when they are old enough to choose a liege lord. Before that, they are considered vassals of the same-sex parent's liege, but are not required to fight.
Some elves are nomadic, others more sedentary. The nomads tend to be hunters and gatherers. The settled elves are experts at high-intensity gardening, with heavy use of magic to enhance both quantity and quality of their produce. Elves are also famous for their magically woven textile products.
Elves tend to have druids more than clerics. They honor their creators, Maddratcha and Madrakka, as well as Ormaz. Some elven loremasters are clerics of Ormaz. Some of the more nomadic elves have shamans dedicated to Leshovik, Kikiejumel, or Leib-Olmai. Elves have no big organized religions. Deity worship is generally a private matter within the immediate family. The clerics and druids aid their people, sometimes trying to steer behavior more into balance with what they perceive as pleasing to their deity. But being independent-minded types, elven clerics won't worship a deity they deem unworthy.
Mostly they are the enemies of the enemies of Ormaz, but not out of love for Ormaz, but because they made their own judgements. Of course, Maddratcha and Madrakka made them that way. But some say the drow turned to evil just to show they had free will. In any case, elves are not prone to following any god's commandments. (If they choose to follow kings who are also priests, well, they are obeying their king, not the god.)
Each elf is subject to the laws of their liege. Kings are held accountable to the other kings for their actions and for their people. The specific laws and punishments vary from kingdom to kingdom, and from one lord to another even within one kingdom.
Elves are generally pleasant, with an amusing air of superiority, except to their enemies (including the people of Angra Mainyu: orcs, goblinoids, etc.) They like to know more about you than you know about them, and sprinkle their speech with ambiguities, riddles, allusions, and other confusions.

Elves do not have names so much as they have songs. The family gives a child a baby-song, which the child adds to as it gets older. Elves select a representative phrase from their namesong to use as a short form of their name. Which phrase they choose varies from person to person, from time to time, etc. Thus, to other races, it seems as though elves have too many names and are always changing them for no apparent reason. This problem is compounded by the elf's tendancy to translate the name for non-Elven speaking listeners.
Typical names: (excerpts from namesongs) Iana-mua (Wondrous-morning), Ilta-kavu'leshki (Evening-birch-leaves), Soosko'aili (Sister-to-waves), Mitainnik (Young-tree-in-the-light), Tuukvayara (Star-on-the-wooded-hill), Velo'aili (Brother-to-waves)
A kingdom of high elves, led by Leaves-blowing-over-the-sea, has a small town in the jungle on Krosa. They have some dealings with the human city via the Warden of the Woods (the chief of the druids on Krosa, a human.) and individual traders and bards.
