1) Ships that approach the Marsiva aren't shot down! We're sorry if we gave that impression - let us know if we need to change something somewhere in the game info! The Marsiva is inaccessible in that there appears to be no way to dock - no way in and no way out.

2) The locator spell would not work! Feel free to have it fail/404 in whatever way you would like to play with, but it will not accurately locate Sam at all.
