For many of the Tsolyáni legions we are missing details such as what the standards and horns they use look like. Here are some sketches I made of proposed standards for (top to bottom):
The Legion of the Joyful Clan of the Noble Vrayáni, 3rd Imperial Slingers;
The Legion of the Twelve Paths of Avánthe, 9th Imperial Slingers; and
The Legion of the Sapphire Kirtle, 12th Imperial Light Infantry.
The Twelve Paths of Avánthe and the Sapphire Kirtle are both Aridáni legions, being composed solely of aridáni women warriors. The Southern Islands are known for their slingers; the Joyful Clan are from the island of Vrá, and the Twelve Paths are from the island of Gánga. The Sapphire Kirtle are javelin girls based out of the little city of Tu'únmra, in central Tsolyánu.
