Prologue
1944
Their footsteps sounded off the walls of the cave but loud boom near the entrance of the cave echoed. They knew that they were getting out of cave alive. Sara held on to Luke's
hand as Stitch the Fox, Tristan and Amber follow them to the location that they intend to placed the piece that would lead to the cursed treasure. But this was time of war and
they acknowledged that the world don't need the end of the world to come. They were scared and anxious that they may failed but didn't break down in tears out of fear for
their ultimate fate.
They succeeded in placing the piece safety hidden within the cave. Knowing that they heard the boom sound that cave is officially cave-in, they sat down on the hard ground
and hugged each others. They rationed their supplies to last them weeks.
As time past without knowing it been weeks or months, they drew their last breath as they were extremely dehydrated and hungry. Luke wrapped his left arm around Sara's wrist holding her as she lied her head on his left shoulder. The fox crawled to Sara's lap and laid there. Tristan and Amber held hands with Sara's left hand and Luke's right hand as they laid their heads on their friends' shoulders. They were admitted scared of going out this way but there was nothing that they could do.
Only to hope that nobody evil could find the piece that will lead to the treasure hidden in Crystal Cove. They kept hopes that somebody on the good side would find them even it would take them years to be found.
Before the war broke out, they was a teen mystery-solving group from the Arch City, and enjoyed solving mysteries. They were known as The Mystery Incorporated that was slowly forgotten shortly after the war.
Without the world's knowledge that they went down in the history of Mystery-solving groups as heroes until the third Mystery Incorporated discovered their existence. The current generation were left wondering what happened to them that caused them to disappeared without a trace during the World War II.
