Elves of all subspecies (high, wood, sea, cave, and quag) are nocturnal. In human cities that also host a large elven population, Elventown is the only place open and thriving at night where you’re not guaranteed to get mugged and/or assaulted. Humans staying for an extended period in Amoth have some difficulty adjusting to the nocturnal life, but once they do, many find it preferable. Flying under The Emperor’s radar is much more difficult in comparison.
