IMC, elves mature into adulthood when they decide to do so. Some are children for centuries, others for only a couple of decades, depending on how much they want to grow up.
I like this, though.
Instead, elven society expected individuals to be incredibly self sufficient, being able to competently do everything from building a house to composing a song. Each elf had to be a warrior, poet, craftsman, artisan, cobbler, smith, historian, doctor, and more before they were considered to be an adult.
I like this, though.
