So one of the things I loved about Golarion was Aroden and the Worldwound. So since I don't know the answer to these either via Pathfinder or Starfinder I thought I would just recreate my own. I am planning on making 2 planets, a moon, and a spatial anomaly. The two planets are going to represent the Lands of Mammoth Lords (allowing me to introduce barbarians with ray guns! lol) and Ustalav (I love the idea of a dark undead world where living creatures struggle to survive sort or like Van Helsing movie). The Castle Moon where Nerosyan was recreated and is in a direct path for what the WorldWound spits out. The rest of Mendev? Who knows but the moon has atmosphere and standard gravity just that the constant battles has forced the citizens of the Castle City (is it Nerosyan then?) to create force fields to protect their farms and basically non combatants civilizations behind the castle city. Finally the WorldWound appears to be some type of black hole anomaly but closer inspection is that it is a wormhole type spatial event. Though not something that could be believed the three have made a trade agreements with each other as none of the areas want to be overrun by what is spit out of the anomaly. So thoughts?
