You want to know about ELVES? Now, there's a curious one.
We all know about house elves, of course. They're the funny little short guys with big noses and floppy ears dressed in pillowcases that cook your food, take your plate and clean everything without ever being seen. Most of the time you don't even know they're there until you call them out, and obediently they will come, only ever speaking when spoken to, not ever asking for a thing return except to give them more work. (And maybe nicer treatment than they usually get. Seriously, they'd make perfect children if they weren't so ugly.)
This is the life of a house elf that has been successfully domesticated to the point where serving is the only thing that gives them purpose, but be warned: they're only ever truly loyal to one master and are fiercely protective of them. Just because they live to serve doesn't mean they live to serve you, especially if you're not the one they're indentured to. Should you get on their bad side you may end up getting a taste of their fury.
(Also worth remembering, house elves can only be freed from servitude when given an article of clothing by their master. Note to self: don't ask house elf to do laundry.)
Wild elves on the other hand couldn't be more unlike their enslaved relatives, like comparing a house cat to a mountain lion. Somewhat taller and married more to nature wild elves live to serve only themselves and seclude themselves from humanity in light of the way their kind are usually treated by the wizarding world. The other profound difference between wild elves to their housebound brethren is in their magic, for while house elves have simple but innate abilities a wild elf has greater use for a wand. While this is in some ways a drawback ultimately it does allow them a wider range of powers to call upon.
Though attitudes have changed in recent times it is still only a rare few who dare to step apart from their tribe as young adults into what is for them a new and alien culture. Despite resentment and conflict on both sides wild elves are for the most part considered the equal of humans but are always watched closely.
