In the player's codex information about places, people, and events, they have encountered is collected, as well as current objectives. This is stylized as a wax tablet, common in the Roman empire as a portable and reusable writing surface.

When players speak to characters they are presented different speech options with different emotional impacts. As pictured, these are coded with representative icons done in a mosaic style.

The Catena menu illustrates the relationships between the people the player has met and themselves. It also signals what virtue bonuses the player can gain from completing objectives linked to different characters.

Throughout the game the player can gain clients, who they can send on missions for rewards and slaves, which bring in a passive income. This menu allows the player to manage them.

The opes menu teaches players about Roman building projects by allowing them to spend collected resources to construct various real-world methods of connections. If done well, the exchange is beneficial. It's largely stylized as a parchment drawing.

Throughout the game players are required to participate in debates with various Roman figures to engage them further with the historical and political material. This shot is an example of one of those debates, and it's UI.
