Culturally, elves are rather authoritarian, with every decision they make being for the state. This is more pronounced in Arumekh lands, but even citizens in other nations tend to be quite conservative, honor-bound, and dutiful. They value handmade everything, particularly any type of thick cloaks or outerwear.
Okay, but like, what's the material culture of the elves like? Are they fantasy-Japan? Fantasy-Persia? Tolkien-style? I need to know what kind of names/clothing/weapons/etc. I would be using if I went for an elf character.
