I've got 3 types of elves in my campaign. Actually, they are better described as three different levels of elven purity. The following is pretty much just copy-pasted from my campaign handout regarding races.
Elves, High
High elves, also known as True Elves, are a very rare race of fey. The high elves are lords among the Seelie Court of the fey. These immortal beings stand almost seven foot tall, are beautiful in appearance and wield potent magic. Despite their love of amorous relationships and courtship, high elves rarely produce offspring (typically having one child per millennia). High elves are an exclusively NPC race and are the nobility of the elven people.
The favoured class of high elves is sorcerer.
Elves, Low
Despite their poor fertility rates, high elves are very fond of love and courtship. Given the scarcity of other high elves and the potential for boredom inherent in immortality, it seems perfectly natural that some high elves would eventually have turned to having relationships with other races, including humans. What was not self-evident was how successful the offspring of this interbreeding would be. The human-elven mixed offspring brought out most of the best qualities of their parent races. Their lifespans were almost triple those of a human and they moved with elven grace. While not as fecund as humans, they bore a new generation about once per century and very rapidly outnumbered the high elves by hundreds and later thousands to one.
While they call themselves “elfborn” in the Elven language, most other races call these human-elven hybrids low elves, or simply elves. To non-elves, the high elves are often near-mythical beings so they see no point in distinguishing between the two races. It is interesting to note that low elves are smaller than both their high elven and human ancestors. It is believed that this is due to the fact that a small portion of low elven ancestry comes from smaller fey races that live among the elves and occasionally have romantic dalliances with them.
In game mechanics terms, low elves are almost identical to the standard elves in the Player’s Handbook. The favoured class of low elves is either ranger or sorcerer (choose one during character creation).
There are no other elven sub-races known to exist, although strange tales of high elves fallen into evil and breeding with orcs or goblinoids do form the basis for some fantastic tales. It is worth noting that elves find these stories highly distasteful.
Elves, Half-
In low elven bloodlines where the fey blood has grown too thin, the offspring grow taller and studier but also have shorter lifespans and are less graceful. These are the half-elves, called “elfcousins” in the Elven language. A small percentage of half-elves are true half-breeds born to a human parent and a low elven parent, but the vast majority of half-elves are simply members of elven families who are so far removed from the original high elves that they now resemble humans more than high elves.
In game mechanics terms, half-elves are identical to the standard half-elves in the Player’s Handbook except as follows. The favoured class of half-elves is bard, ranger or sorcerer (choose one during character creation). To compensate for losing their “any” favoured class, half-elves receive +4 skill points at first level and +1 skill point per level thereafter, like humans do, to reflect their human heritage.
