Time Capsule (94, 89)

Time Capsule (94, 89) - A polished granite disc twenty feet across bears markings in an ancient script. The language has not been spoken in eons, but it is well known to scholars. The words say "Our future is your past." This is a time capsule left by those who lived here ages ago. It has so far been impervious to all attempts to open it. When the time finally comes, it will reveal a small library of long-lost works of ancient knowledge including an entire school of magic which was suppressed as too dangerous to be used in the world.
