The Solar Imperium before the war was one of Swagistans closest allies, collaborating in military, diplomacy, and many other national fields. However, after the civil war broke out, they've mostly stayed silent in diplomacy and material support, however, unoffical volunteer groups from the Solar Imperium started flooding into the Libertarians controlled lands in support of them, mostly due to Magis ties to the country and their aims for a democratic country.
The Kuibletz oil rig before the civil war was one of Swagistans most prized possessions, being one of the biggest producing oil rigs in the world. After the civil war broke out, it offically declared its independence after the initial chaos on the mainland, seizing a few islands around itself in the process, it could do this due to its influence and unique patriotism it had over its residents. Their diplomacy with their only neighbour, the Libertarians, are friendly, (some of that due to the power balance, or lack thereof.) In light of this, they gave material support to the Libertarians, being their copious amounts of oil, achieving relative autonomy for the time being, this had also helped the FFB indirectly, with some of that support going to them through the Libertarians.
Commonly shortened to the PSO, they're an inter-galactical force tasked in defending humans from hostile pokemon on several planets, using the elusive stargate for transportation throughout worlds. When they originally made contact with Swagistan, postive relations and material support followed suit. When the civil war broke out, the Central Government, unlike all other instances of foregin support, were given resources instead of the Libertarians.
