Don't go into Hollows. I know, I know, there are Ether resources in the Hollows, bizarre creations, even ruins of the old civilization — all invaluable treasures. But don't forget about the spatial disorder, the monsters, and mutants running rampant. Ultimately, this is a disaster that could swallow the world. Hollows are not where ordinary people should go. So don't go into Hollows. Or at least, don't go in alone. If you insist on getting into danger, go to New Eridu first. This city full of people from all walks of life has many who need the Hollows: powerful and wealthy tycoons, gangs who rule the streets, schemers hiding in the shadows, and ruthless officials. Make your preparations there, find strong allies, and most importantly... Find a "Proxy." Only they can guide people out of labyrinthian Hollows. Good luck.
