Locations that exist in BossfightsX's world and how they're different
The Citadel - A lifeless husk of a city floating through the cold depths of space, made up of long and large labyrinths made up of titanic abandoned buildings. Destruction in the area is minimal, you may run into the occasional fire or broken window, but the area is otherwise untouched, leaving only an empty and errie atmosphere.
Yukuna Manor - Essentially BossfightsX's equivalent of Hill.Gym/X's Castle. The halls have shifted in hue from a soft blue to a deep violet, and all the paintings and furniture that line the halls have been replaced with imagery depicting X's likeness. The manor has become more like a castle in some ways, with basements turning to dungeons and a throne room for X. The rooms of the Yukuna family remain, and while those who occupy them resemble the Yukunas, they certainly are not the family.
Broken Earth - In complete and utter ruin, in what remains of the crushed cities, you can find the littered corpses of members of the Pantheon, Coritans, Xanthiel, as well as civilian humans and aliens.
Tinted Earth (totally different planet than Broken Earth, trust) - Reverted back to its old status as a dead planet and even further beyond. The environment is extremely hostile, with rapidly changing weather, extremely hot and cold temperatures, and stone-infused monstrosities that roam with no goal but to hunt. Xerxes can be found here, but not as any sentient being. A creature of stone and flesh intertwined into a web in the planet itself thst only exists to consume.
