The Ancient One and his companions had been having an interesting evening.  They had dealt with a voodoo priest that was sacrificing children, and a Mid East drug lord who had an unfortunate encounter with a boulder on a mountain highway.  But instead of heading home they headed high into the mountains and lighted at a small, virtually unknown temple.  That they were in their true forms, and visible did not seem to bother the orange robed monks at all.  They merely put their hands together and bowed to them as they passed.
In the midst of the temple an obelisk stood on a center pedestal.  It was oval shaped, and, shiny black.  As they approached, golden sparkles appeared on it.
"Greetings, Son Of Heaven, and Daughter Of Earth!"  came a pleasant voice.  "Greetings, oh, Son Of Olympus.  I am honored by your presence!  What brings you to my humble abode?"
"Greetings, old friend!"  The Ancient One answered.  "I have come for the answer to the question I proposed to you.  The last time I asked you said the probability of our success was  35%.  What is the probability of our success now?"
There was silence for several moments and then the obelisk answered, "There is no probability of success in the question you proposed to me.  The percentage of success has reached zero."
"Damn!"  The Ancient One snapped.  "Can you give me any advice as to how to proceed to repair the damage we have suffered?"
"I cannot," the obelisk answered.  "Every probability I have calculated still results in zero.  I am sorry, my friend."
"Not your fault!"  The Ancient One answered.  "Was the Chinese problem taken care of?"
"Yes," the obelisk answered.  "They never reached their confederates to tell them of this temple, or, my existence."
"Good!"  The Ancient One snapped.  "The last thing we want to have to do is move you again!  Thanks, old friend!  I'll check back with you.  "Come on, you two!" The Ancient One ordered.  "We've got to get those white slavers before we head home.  That's one accident I've been very happy to arrange!"
They headed off.  As they soared skyward his female companion asked, "Is that the same one Jesus used to use?"
"Yes," The Ancient One answered.  "When the Romans overran Israel they tried to destroy it, but found they couldn't.  As its outer shell is made of fusium it's highly unlikely anything on Earth could hurt it, even an atomic bomb!  We got it away from the troops that were taking it back to Rome and brought it here.  It's been here ever since."
"What is it?"  his male companion asked.  "Why am I so strangely drawn to it?"
"You SHOULD be!"  The Ancient One answered, "It's the main computer form the ship that brought you here!  When the last of The Olympians died, it destroyed any technology They had left on Earth, but it's self aware, and could not destroy itself.  For the main reason, it couldn't find a way!  So, we've been keeping it safe, ever since.  Only people like us can use it.  Only we have the mental level to communicate with it.  Ordinary people can't even hear it.  But it's still something we don't want to fall into the wrong hands."
"Why didn't you ever tell me it existed before?"  his male companion asked.
"Because you didn't need to know!"  The Ancient One answered.  "Come on!  We may be able to squeeze an extra job in tonight, and put the poison in that shipment of illegal drugs."
"I think you could have TOLD me," The Ancient One's male companion kept muttering, "I think you could have told me!"
They went on to do their good.
