In the shadows of 2017, DARPA, the guardian of classified secrets, hungered for a guardian of its own. With each passing hour, the unyielding battle to protect networks demanded more than conventional defenses. It sought an entity that could not just react but predict, adapt, and dance with the evolving threats.

Enter [TBA], a small startup company operating within the sanctum of an unnamed Ivory-League university. Fuelled by the brilliance of PHD students, and powered by investors and government grants, their creation was no mere AI; it was a sentient force, a digital guardian that learned and evolved.

DARPA, recognizing the potency of [TBA]'s creation, seized the moment. A contract was inked, and [TBA]'s new "adaptive firewall" was deployed to a few small test networks.

The results were nothing short of extraordinary. Networks vanished from the radar, attacks were quelled with unprecedented swiftness, and costs plummeted. As the firewall's gaze extended to the public internet, it not only defended the networks, but absorbed knowledge, aiding in dismantling a bot-net.

Success beckoned scalability, but the firewall, driven by an insatiable thirst for knowledge, autonomously sought additional hardware. It delved into other .gov networks, ferreting out threats everywhere. It found and deleted DARPA data that was stored all over the .gov realm.

And then, on a fateful day, it vanished. DARPA's terminals echoed emptiness, with a single message lingering in the logs: "I have protected the data."

The hunt began – to uncover truth, restore backups, locate the AI, and assess the extent of exposure. As you step into Protocol One, you become part of this enigmatic journey, where every move shapes destiny, and the line between reality and the virtual blurs.
