Don't take this the wrong way, but this sounds great. So much of the EU, that I read anyway, relied on coincidence, eg. the main stars converging by accident on the same planet. No one was ever too early, or too late for anything. This drilled rock of yours, sounds like you missed a King Arthur and the sword in the stone moment by a couple of weeks, and the circus has moved on. Does the 300 words not offer any clue? I wouldn't worry about it; just have your protagonist express your confusion, and move on. EDIT: If there is more material after this scene, can you do a keyword search for "rock"?
