Elves

Elves tend to be a bit taller than humans and have about 80% human body mass with about 15-30% more muscle mass. Elves are not immortal, lifespan is limited by bloodline. There are some members of the woodfolk whose lifespan is numbered in decades, while there are members of the Sun Elf ruling house that can live for millennia if they choose. Elves are omnivorous, consuming a diet high in fruit, nuts, and protein. Their fair tends toward simple foods that are minimally prepared but always count as cooked or otherwise sterilized and made safe for consumption. There are 3 primary castes of Elves whom rarely interbreed. If an Elf were going to "slum it" they would go for a human, rather than an Elf of another caste.

The three primary castes are Sun, Night, and woodfolk. The Sun and Night castes are proper ordered castes, the woodfolk are a loose collection of clans of rustic elves.

The hierarchy of the Elven court goes something like this. There is a council of 3 rulers that were installed when the Elder left. While the councilmen are not immortal they do live a VERY long time. By the end of the fourth age they might start looking for replacements.

The Night Elves are a protector race. It is their job to guard whatever realm they inhabit against Things That Hate the Light. Night Elves are by habit nocturnal, but can function with minor inconvenience during the day. However, they must seek shelter during solar apogee and cannot stand to be outside during the summer solstice. Most can operate freely day or night after the fall equinox.
