I'm growing rather impatient with you modern day Grifix. Who's to say January 1st is the official date I come for the crown? I can arrive earlier than that. I may actually, already, be among you all this very second. You all have figured out a "hobby" of mine following encryptions and ciphers. I grew up on these messaging systems, I was abused by these messaging systems, and I will use these systems to not only expose your historic lie.

I will rewrite OUR history, so, I leave you with this new encryption.

NO HINTS!

Except...maybe just one, and only one
