Alien labyrinth, actively hostile
One of the ancient Talismans of Vaul, adrift and mostly awake. Its interior rearranges itself, it is worth a fortune to anyone who survives it, and something inside it is doing the rearranging on purpose.
Position
Map frame: 88, 652 in the archive's 0–1000 disk space (core at 500, 500).
Distance from the core: 439 units ≈ 46.7k light years, south-west of the galactic core.
Height above the disk plane: 1.5 units — invented thin-disk jitter, deterministic per record. No published source gives any location a z coordinate.
Every fact in this record, and where it came from. Editorial derivations say so.
