What? My "Information Club" is Actually an All-Knowing Secret Society?

In the burning heat of Jakarta, Arlen is a broke car wash employee with one last hope, his unpublished novel The Frozen Era. Knowing that nobody reads books anymore, he decides to sell "experience". He makes an Alternate Reality Game (ARG), hiding impossible puzzles across the website, application, and even real life place on another city, to find the smartest readers for his story about a tropical apocalypse. He expected to find bored gamers, employee, or maybe some broke people like him. Instead, he recruited a group of dangerous strangers. These elite few cracked his codes and entered his secret chat room. They are convinced that Arlen, "The Architect", is not a fiction writer, but a whistleblower leaking secret information from the future, about the end of the world. Whatever Arlen writes in the chat, suddenly all his followers find a way to justify the reality to it. The ice is coming. And the only person who thinks it’s all fake... is the one who wrote the script.
