Things from the Flood timeline:
Late 1994: Riksenergi is privatized and the name is changed to Krafta.
October 1994: The Loop is shut down.
Winter of 1994-95: Dark water floods basements, cellars, and low-lying land close to the Loop, the local population is evacuated.
Mid-1990's: AI pogroms in Russia cause robots ("vagabonds") to migrate. Some of them end up in Sweden, where they settle like metal illegal aliens.
January 1996: An incident prompts the Police to round up all "vagabonds" and have them destroyed.
1996: A mysterious plague affects robots, machinery and electronics in the flooded area. There's speculation that it is caused by some sort of virus that originated from 51 Pegasi B, after a failed portal experiment. Strange, insectoid creatures appear.
Spring 1997: Swedish Army bots arrive to help Krafta clear the area.
October 1998: The area is declared cleared and safe. All above-ground installations have been dismantled, while the Loop and other underground facilities have been filled in with concrete.
2001: A magnetic polar shift wrecks magnetrin shipping for good.
Roleplaying in the 1990's setting would mean more danger, suitable for older characters (about 15 years old). Perhaps younger siblings of the kids who experienced the mysteries in the late 1980's?
My life fades. The vision dims. All that remains are memories. I remember a time of chaos, ruined dreams, this wasted land.
