I read something, and I’ve got things to say about it!
Cryptomancer, “a fantasy role-playing game about hacking”, purchased via drivethrurpg.com as print-on-demand hardcover.
What this is not: Shadowrun in a fantasy setting. Sorry if I just smashed your expectations, but I wanted to get that out of the way. So, what is this, then? Glad you asked.
Cryptomancer is a fantasy RPG with mechanics for instantaneous, but not inherently secure communication using crystal shards and the innate-to-all magical ability to work cryptomancy, a magic form of cryptography. You wont roll on hacking, though.
