We want to unite the Houses and, once this is done, wage an open war of extermination against Nomads
Secondary objective:
Claim Sirius for Humanity.
Background Story:
The madness made us become almost a family...But really, how could we possibly live knowing that an alien species (likely the same ones we met in Chester. It wasn't hard to connect the dots) was still out there, possibly planning and scheming their second coming, wich would result in another madness and a potential annihilation of humanity?
So we found a political party, wich we deemed "Humanity First". We were asking one politically united, compact humanity. We knew that, if these aliens needed us as vessels to make us wage war on eachother, if they wanted to destroy the remnants of us by just appearing out of the blue and annihilating one by one our weakened forces, instead of waging an open war against us since the beginning...then they were a quite weak species, after all. It was quite evident that their capacities were limited, if they needed us weak and divided.
But united, with our combined resources, we could fight them, starting even from that moment and ultimately crushing them within a year or two, so we propagated our ideas and even participated on various planetary elections, where we had an obscenely high amount of success among voters.
But really? One humanity? No Houses? No governments? The ruling classes knew that, with one united humanity, they would've been changed, replaced with someone else...so they started with the defamation. The struggle later on got rejected by the House Governments reasoned "against National interest". (Everything happened after this, all the Criminal organisation and such are hereby RETCONNED.
