Allies of Rome

The Allies of Rome are a non-playable Latin faction that only appears in the very beginning of the Pyrrhus Campaign of the Eagle King DLC, owning two camps in Iapygia near the player's starting point that make up the player's first combat challenge in the campaign.

These camps are located away from the main part of the territory of the Republic of Rome faction and can therefore not be properly supplied with food, which is presumably why a separate faction with a -100% Food Consumption attribute was created for them instead, with an added morale bonus to slightly buff them. The faction simply re-uses the logo of the Republic of Rome faction.

In-game Description
"Tribes that favour the Romans and .."

(The faction description seems to have been left unfinished, presumably as an oversight by the developers).
