Prelude

Shadow-Orovika War

Prior to the establishment of RentDueYesterday, several of the players who would go on to create it, including FellOffBridge, AdelieXY, and Noix444, fought for the nation of Shadow (then under the control of Ae0n) in a smaller conflict against Orovika.

This conflict, which lasted from 22 August to 29 September 2023, is widely considered to be a progenitor to the Horizon Federation-RentDueYesterday war, as it involved many of the same players fighting one another on the same sides as the Horizon Federation-RentDueYesterday War would. Several pirate players involved in the conflict (most notably FellOffBridge) transitioned seamlessly from fighting Orovika for Shadow to fighting Orovika (and others) for RentDueYesterday, even after peace was struck with Shadow on 29 September.
