Aatilon is a fan-made tribe created by The Bhalk. They are based of hun or hungarian culture.
Field: darker green
Fruit: Potato because why not
Mountain: green like the fields and not so high
City: Yurts, but on top of each other
Head: Green painted face (not based on William Wallace), black hair with two ocher feathers in it.
Tech: Chivalry (modified), doesn't spawn with a knight.
The Aatilon has lots of Forests and not much Mountains. They have a modified Knight unit, not having the ability to persist but having a range of two. So they are Archer-Riders.
Side Note Edit
The appearance of the Aatilon tribe don't look like the huns, huns look more like mongolians. And yes, huns and hungarians are really not the same.
