The Girl in Glass
Alianus is an elf nation in the northern part of Tanelorn housed mainly in an ancient wood with massive trees. The elves have lived in the wood for thousands of years and despite numerous attempts by invaders to take the land it remains inviolate.
When the Gray Lord arrived in the area fifty years ago the elves were suspicious but he recently won them ever when he helped repel an Gnollish invasion and they have become part of Tanelorn. They serve as archers in the Gray Armies and many have Taken the Gray Oath although no foreign army is ever allowed in Alianus proper.
Even solitary strangers are killed if they attempt to enter the wood without express permission. The elves are ruled by a king and worship a pantheon of ancient dieties no longer recognized in most places of Corland.
