Level up! My safe zone is kinda weird!

Riley was not prepared for any of this. One minute, she was an office drone drowning in spreadsheets, the next, the sky was bleeding, horned monkeys were falling from the heavens, and reality had been hijacked by some kind of apocalypse-slash-video-game-from-hell. But as some wise man - or maybe just a desperate voice of self-preservation she invented on the spot - once said: it was better to continue existing. So, Riley would continue to survive. She would take the next step forward. Look, she couldn't exactly go out and dominate the world, slay all the monsters, or do any of the big, flashy hero things. But what she could do was operate her bizarre skill. She had a Safe Zone, and by God, she was going to make it the absolute safest goddamn zone this ruined world had ever seen. But wait... why was her Safe Zone so different? Why did it upgrade to an unheard-of SSS-Grade? And how was it that her fortress of absolute solitude... could do all these things? Friends!
