Who gets it: Aetolian League

Priest of Apollo: The Aitolian Assembly has assembled! To discuss: A proposal by the Kalydonians.

Aitolians:

Kalydonians: Brave men of Aitolia! We know you are the boldest warriors and best men of Greece!

Aitolians: Yaaahhh!!! Aitolia forever!

Kalydonians: Yet, ahem, we suggest an improvement for our army.

Aitolians:

Kalydonians: We brought with us new armour from Macedon, including Galatian chainmail, and shiny new Aspis shields that can be held by the rider of a horse. Allow us to equip our soldiers with these items, and we will be invincible!

Aitolians:

Thermonians: What does Apollo think?

Priest: I will read the auspices!

Aitolians: By Apollo!

Priest: ... I can see it. Yes...yes! Apollo wills it! We shall introduce the new regiments. I have spoken.

Aitolians: Yaaaahh! Aitolia forever!
