Elves... a standard fantasy race, those pointy ears are found everywhere - I've played enough of them. But here's a new twist or two, a few ideas for elves as other than flower-bestrewn, nature loving, musical and magical folks.
Variant races, or at least distinctive communities who may or may not be an actual different sub-race (we'll let the geneticists decide!). There's the necroms, who have become obsessed with longevity to the exclusion of everything else - including good taste, never mind ethics, to many people's opinions... although they rarely care what other people think of them anyway. Given their tendency to play it safe and avoid taking risks (well, in person, anyway), they might make an interesting NPC colony, although full details are provided should anyone want to play one.
Then there's the twistborn: elven shapeshifters who have become specialist spies and infiltrators. In their 'natural' form they are nowhere near as good-looking as most elves. They cannot interbreed with other races, being fertile only with elves and other twistborn, and are generally found in their target community or back with the elves. They generally become adventurers either when sent on a mission or for purely selfish reasons; and are often found doing their best to fit in and make themselves useful to the party they've joined. Definitely some potential there!
Several feats suitable for elves (any sort, not just necrons and twistborn) are presented, interesting ones include craftsmanship, enhanced lowlight vision (called moon runner), and ones involving their close bonds with nature and utilising their longevity to give them increased knowledge of lore... some nice stuff here.
If you are using Flaws - as introduced in Player's Options: Flaws - there are some elf-specific ones making good use of the stereotypes of elves: arrogant, disdain, laziness and even a sweet tooth! Finally there are notes on elven armour, equipment and item qualities to help you bring a slight air of otherness to the things that they make.
An interesting little collection, particularly if you enjoy the little quirks that make each race (or even sub-race) distinctive and different from each other.
