The city of Silvermoon had Faeruns as its majority.
They looked like humans except for their pointy ears and exceptional attractive features. They also had a coppery range of complexions that made them stand out from the group of humans.
The Faeruns were indeed species of elves that were reclusive, insular, feral and stealthy in nature. They preferred to remain close to nature and were rarely seen by other races.
The Faeruns had their own customs and beliefs, most of which revolved around the concepts of predator and prey or life and death. They behaved in moderation with other races, including other species of elves. But they were also known to be fierce allies to those they consider their friends.
Most Faerun ladies would join Amazons from a young age because their ideologies synched with the core values of the creed. That's why the Faeruns held significant sway over Amazons.
