At the start of the series, the Republic of Regium is engaged in a costly war with the Federation of Dragnov. Dragnov wanted to reunify the two countries, but Regium was bitterly opposed to this and mobilized their army instead. In part due to winter conditions, the Regium forces had the upper hand at the start of the war, but gradually the Dragnov forces came close to overrunning Regium's last line of defence around the capital of Solgrenne, until Dragnov launched a new missile that caused serious damage to the capital despite being detonated indirectly 8 km outside the city, which convinced the Regium politicians to negotiate for a surrender, although the Regium Third Army refused to surrender and continued fighting.
