Ruinfall caused the apocalypse on 6-27-23. He will appear: Halloween 2023.

Invest in apocalypse quantum now: on Halloween there will be a blood (money) drive to purchase shares in the apocalypse. (This is like beta-test buy-in, it has a special value and will carry a special prestige and is therefore rare and worth any investment of any sum.) Hint: this is the quantum to purchase. Don’t get caught post-Halloween with your pants down. Save now, invest then.
