Ah, share spell, clever.  :)<br/><br/>You might have to bring back the survivor and hope that the illusion gets the attention of those who will raise the other three.  Alternativly, if the survivor is concious, leave him with an offering for the priests who might cast raise dead on behalf of the slain (at least enough for the diamonds) and count on the signal flare to bring them.<br/><br/>Problem with that is it's leaving a living being on the atol while we wait for the bird to come back...
