Reise stepped cautiously toward the box. Although it was small enough to fit on a cluttered desk, it looked resilient enough to survive undamaged if the entire building was demolished. The main material element seemed to be stone at first glance, but as Reise looked closer it became more obvious that the patterns on the flat sides had been etched into robust, dark metal. Holding the sides together was a frame of even more mysterious make, pulsing faintly with purple light that coursed around and in between the metal plates to form a hexagonal prism shape, rigid and angular with glowing purple spikes branching out of its corners. The glow shone brightest within a line that cut straight through the middle of each of the box’s six long faces, and Reise concluded that this was the separation between lid and base, the way the box would open. But it wouldn’t open even a fraction of an inch while the lock was still engaged. On the front of the box, lines had been dug into its flat face to create thick, circular trenches in a highly specific pattern. Reise focused on the pattern, training their eyes on the directions of the lines and mentally retracing the way they assumed it had been written. As they did, that unknowable voice spoke up in their mind once again, in a tone that was forceful yet calming, a voice flooded with dozens of emotions Reise had never felt.

“OPEN,” was the word the voice gave.

“You know what? That one was painfully obvious,” Reise mused as they pressed their finger to the start of the first line.
