At the beginning of 31 BCE, Neptune opens up Actium for a naval battle by blowing on a conch calling all players (living mortals, imagines and numina) to the proelium ultimum (the final battle) at Actium which will decide the fate of the Roman world. All players with properties must participate in the proelium ultimum as active parties or their allies (amici, clientes). Amicitiae ultimae (final alliances) may be formed at this time. Imagines and numina may contribute whatever Denarii and other properties they have remaining to any party involved in the proelium ultimum.
Before the Battle of Actium, all players must redeem the properties and Denarii in their possession, exchanging them for naves longae (warships) purchasable from Neptune at the costs listed in Appendix B. To facilitate this process, players must fill out a form listing all their properties and their values and hand this form to Neptune in exchange for naves longae. All numina will help Neptune with this process.
Naves longae can be purchased from Neptune, according to the following values:
- Legio (curialis or clientarum): 400,000 D
- Classis: 300,000 D
- 10 Suffragia: 100,000 D
- Rexpressus Platinum: 3,000,000 D
- Legiones ultrices (belonging to imagines or Mars):
- Dos: 3,000,000 D.
A party engaged in the proelium ultimum consists of any active player (and his amici/clientes) who is in possession of at least one navis longa. Because this conflict takes place at sea, unlike in land battles all parties engage in the proelium ultimum simultaneously and fight each other at the same time.
The proelium ultimum proceeds as follows:
- all parties roll one die simultaneouslyand Neptune announces out loud the number on each die and then proclaims the victor of that concursatio navalis
- if one player rolls a number higher than all others, he retains his
own navis longa (die) and all other players lose theirs to
- if two or more players tie for the highest number, they retain their
naves longae (dice) and all other players lose theirs to Neptune
- play continues until only one party is left in possession of one or more navis longa
Any non-mortal player (outside force) who is in possession of a legio of any sort may participate once during the Battle of Actium, acting in the same way that imagines do during the course of the Game. That is, outside forces may add the total of one throw of their die (legio) to the total of any party's roll. However, once a numen has participated as an outside force, s/he may not do so again. The Fates are responsible for confiscating an outside force’s die after it has been used and keeping track of which numina have participated as outside forces.
- Outside forces include all imagines, bacchants and numina
(including war-gods) who have a legio of any sort in their
possession when Neptune opens up Actium for the proelium ultimum.
Each single numen, imago or bacchant constitutes one
individual outside force.
- Any number of such outside forces may roll their dice in favor of any party during any single concursatio navalis.
- Outside forces must declare out loud their intention to add their die to the total of one party before Neptune has proclaimed the victor of the concursatio.If there is dissension about the timing, the Fates will decide whether the declaration of the outside force was made in time.
The victorious party leads a triumphal procession around the world, ending in Rome. They may shout "Io triumphe!" and sing apotropaic verses, praising and/or abusing their leader. After arriving in Rome, Juppiter Optimus Maximus bestows on the leader the corona triumphalis (the golden crown of triumph) and the title "Magnus/Magna."
The victorious party is now in control of Rome, it may organize the
Roman state at will, establishing any type of government (e.g. Republic,
Empire, Democracy, Loose Confederation of City-States or Tribes, Thiasos,
an Autonomous Collective as part of an Anarcho-syndicalist Commune, etc.).
It may dispose of all parties, including numina, in any of the
- enslave or kill any survivors
- assign to any survivors the governance of a region or regions
- deify and establish the cult of any imago
- promote or forbid the worship of any numen
