Overview

Cryptographic User Makerspace, abbreviated CUM, is a private cryptography forum in Scenebux. It hosts discussion of old cryptographic puzzles, including unsolved Aeschylus puzzles that can lead toward T4 Fund contacts.

Role

The Syndicate Deutschland head of meatspace kinetics gives Ben Etxina the forum name after Ben asks about T4 and Aeschylus puzzles. Ben gains access by solving an entry riddle and then reads the /sock/ subforum.

While quarantining in New York, Ben uses material from CUM to solve an Aeschylus puzzle. The solution yields an email address, and the reply sends him to the Bullman Building appointment that leads to the Young Realists and Gabriel Findhom.
