The Sword and the Star
The crew of the Kaleidoscope Factor Five, a ship you rescued, told you of this plane. Sonya Starson was also in this sector. Goddard, the captain of KFF, informed that notable systems are North Spirit, Paradise V2.0, Wei Xiu, and Doctrina.
North Spirit, apparently, has multiple polities in the same system, unlike most prominent systems in the Draconis Sector.
Paradise V2.0 is some sort of dystopian control state that uses a brain-infecting fungus to enhance the susceptibility of a portion of its citizens.
Either in the rimwards area of the Weyrd Sector, or a little bit further than that, is The Monster at Torus.
