First Rissa War

5323AD–5335AD. A conflict fought between the Scybrian Polyarchy and the Firstworlds over trade rights along the Scybrian Run star lane. Part of the Mid War period of the Scybrian Wars. The Firstworlds began aggressive customs searches of vessels crossing the Rissa Gateway, ultimately resulting in the destruction of a number of Scybrian merchant ships that refused to comply. Scybrian naval forces began escort missions and very quickly the situation devolved into a full-scale naval war.

Scybria launched an assault and overran a number of worlds in the Rissa Gateway, including Rissa itself, and occupied two systems in Far Home sector. The experienced Scybrian forces did serious damage, though they faced a near fanatical defense from the isolated outposts of Firstworld troops. At around the same time revelations about Scybrian involvement in the Hidden War enraged the Firstworlds and propelled a national effort.

The conflict descended into a grinding war of attrition marked by occasional naval skirmishes and commando raids. As both sides neared exhaustion an armistice came into effect. The war was finally ended after protracted negotiations that involved disbanding the the People's Liberation Front.
