The Avedian Reich offers an alliance to the Atlas Empire. In case of a defensive warfare support has to be granted, if one of the signing nations wages a war of aggression, the other one has at least to hold benevolent neutrality.
The offer is personally written down into a letter by the Emperor himself. Here you can see the handover of the letter to the Chancellor of the Realm (responsible for foreign affairs) in the small throne room. He will bring it to His Majesty the Emperor of Atlas.
