First: About Ilsa and Ilsarians
An elf city, built in a Forest of silver trees, ruled by king Aldarion and queen Tauriwen, is said to be the most beautiful Kingdom of them all. The white horses of Ilsa have silver crests, their fields wave in the silvery wind. Stars are always silver on their sky, and in the eyes of all Ilsarians.
Second: About the picture
It represents an Ilsarian girl, dressed in regular Ilsarian clothes. A brown top on a white gown, sometimes coloured slightly green. Details on the sleeves and the top are a bit off because of the scan.
