"Hello, dear. I hope the journey wasn’t too distressing. Cortex handles security system design and management for the government, so I assume the camp will follow standard protocol—DNA coding on track pads next to secure doors. If you find yourself stuck at a door, hold this card on the plate and wait. The hacking system is smart but not invisible; they will know something compromised the door, but it’ll get you through. I’d expect them to come fast, so use only if you have to. Good luck, stay safe."
