Vault‑Grid Bulkhead – Plain Sci‑Fi Wall

The Vault‑Grid Bulkhead is a deceptively simple slab used in high‑security research vaults, its seamless tiles hiding armored foam, sensor webs, and emergency grav‑locks. Station crews joke that if you stare at the squares long enough you start seeing doors and consoles that aren’t there—right up until one silently irises open for authorized personnel. Use this clean panel as a blank canvas for kitbashing corridors, data‑vaults, or underground bunkers, letting your adventurers wonder which section of the wall might suddenly become a hatch, screen, or firing slit.
