Prologue: Museum Heist

Somewhere in Prague 8:30 PM

In the dark streets of Prague a shadowy silhouette was running on the rooftops. The shadow continued to run, until it jumped off one of the roofs, grabbing some pipes and flag polls to safe fall to the streets, and soon reached the light of a lamp post, revealing who it was. A female human in her teens with black short hair, wearing a black t-shirt, black shorts, black backpack, black cap with black goggles over her head, black finger less gloves, black tennis shoes, and holding a black staff with a white diamond. There is also a creature that is known as an ottsel (a hybrid between an otter and a weasel) on her left shoulder, which also appears female, and also had orange fur, but blonde hair, wearing a green, heavy-duty top that stop above her midriff withe brown suspenders and denim shorts, with a magenta headband over her head showing behind her ears.

The human female looked up and saw the location of her destination, a huge building with a glass dome with a minaret which means its a skylight. The girl looked at a sign next to the entrance to the building it read "Prague's Museum of Darkness and Villainy." The girl saw a some guards coming, and also saw some windows that look stable, so she went and began climbing until she was at the top of the museum and notice it was clear of guards, so she and her little partner could rest.

The teenage girl felt a vibrations on her goggles, so she put them over her eyes, and soon the girl's face is shown on her right goggle's lens, and on her left goggle's lens shows a green anthropomorphic box turtle wearing glasses and a red bow tie. The turtle then said to the human girl, "Taylor, come in, Taylor, do you and Tess read me?" Taylor, the girl, replied "Yeah we both hear you very loud," the turtle then said, "Sorry my friend, I am nervous that I am helping a new friend do a break in while I'm still trying to find any clues about what happened to my best friend, Sly Cooper, after the events of the time changing scandal orchestrated by Cyrille Le Paradox, especially this break in is going to be in a museum based on villains and the darkness they did or did not participate in." Taylor told her turtle friend, "Get over it Bentley, your safe in the SUV with the Captain, I know it is wrong to steal, but I really have to get that Dark Diamond before it falls in the hands of the clone of that big floating tub of lard Krew," Bentley replied after making a disgusted face when Taylor made the remark, "Thanks for that image, anyway I scoped every spots of security in the museum it seems most of the active guards are outside, while the interior guards are either distracted or sleeping, and not anywhere near the diamond, the fastest way to get to it is an air vent that is somewhere near you and Tess," Taylor then said, "Thanks I'll find it and use it." Then the left goggle lens switched from Bentley to a human male that looks strong, wearing some green tights that hides his head except for his mouth and big chin, and on his chest, a blue and black atom with a lightning bolt that vaguely resembles the letter "Q" came one. The man then told Taylor, "And don't forget you and Tess have me as your get away Taylor, all you have to do is get the diamond and head back to the SUV, me and Bentley will do the rest." Taylor replied back, "Just keep that engine in that vehicle running Qwark, we'll be down with the diamond in no time." After the conversation, Taylor took the goggles off her eyes, and back on her cap.

Taylor soon began looking for the air vent, while she was doing that, Tess soon began to talk, "I can't believe my cruel boss was cloned, I thought my Daxter and Jak left him to die in an explosion in the Secret Weapons Factory, how did that happen anyway," Taylor replied, "I don't know how it happened, but whoever did it wanted to give that living gas ball a second chance, wait a minute I found it." Taylor soon saw the air vent in the wall she tried to open it, but it wouldn't budge, but soon Bentley said through an earpiece communicator in her left ear, "Try using your staff to break the grates to get in," Taylor then did that and they can go in. Taylor let Tess go first, then she crawled to follow her. She soon touched her communicator and said, "Bentley can you help me and Tess, the ventilation system is like a maze," Bentley replied, "Hang on, okay I see the spot where the Dark Diamond is being displayed is at the end of the of the shaft, if you see a split, go left, but watch out the is a drop, I hope you go first so you won't harm Tess by accident."

Taylor and Tess soon followed Bentley's directions, and were in front of a grate. Taylor looked through it and saw many artifacts that were used by villains of Sly Cooper, like mask worn by Don Octavio, the crown that belonged to The Grizz, stink grenades from Le Paradox, even Penelope's Black Knight suit. Taylor is still wary, she put down her goggles, clicked a button on her right goggle lens to have infrared vision, and saw lasers. She soon disabled the infrared, and twisted the goggles lenses as if they were binoculars, looked around, and saw her prize, a medium-size black gem. Taylor soon said to Tess, "There it is, my friend, the Dark Diamond, though even with the lasers, it's still too easy." She soon clicked a button on her left goggle lens to have x-ray vision, and saw an old security mechanism. She then said, "I was right, its a pressure plate, Bentley, can you turn off the power here so I won't trip any alarms." Bentley replied, "Okay, disabling the security systems, there, all clear Taylor, I'll turn it back on when you get the diamond and be safe."

Taylor the pushed the grate with her foot, and soon it gently it began to get off the wall, she soon slid the grate to her left. She and Tess went to where the Dark Diamond is, in a glass box with a three number combo lock. Bentley soon said, "Way to go Taylor, don't worry about the lock, I hacked into the museums' security and found the lock's code, try dialing in 8-4-8." Taylor the dialing the combo, and soon the glass opened. She soon took the Dark Diamond, opened and put it in her backpack, took out another gem similar to the diamond, and put it in its place. Taylor then told Bentley, "Good thing you have this black gem made of glass to make sure that Krew won't see the difference until it's too late," Bently replied, "Thank Dimitri Loustaeu, it was one of his creations during his art forgery days, never knew it would come in handy." Taylor then closed the glass box, and set the numbers back to 0, took a rag from her pocket, wiped off the glass and numbers her fingerprints, then Qwark came on and said, "Nice job covering your tracks now head back the way you came, head back to that lamp post, we will come and get you in the SUV."

Taylor soon went back to the air vent, and slide the grate back, and said, "Okay Bentley, you can turn back on the security," Bentley replied, "Security back on." Taylor and Tess started to climb up, after they climbed up and began crawling back the way came, and saw the light, but just as they were about to leave, they heard a voice coming from below. Taylor saw another grate, and looked through it and saw an uncommonly large human with acute obesity, with small and gaunt legs which revokes his possibility of walking or standing on his own so he is on a hover chair type device called a floating grav-basket, which supports his body also shines some sort of light over his head. He is also bald and has pig-like facial features, with stubby ears and an obese, vexed facial expression, as well as many piercings, and wears a light green tank top shirt, and dark green shorts. Taylor knew that is the clone of Krew, while Tess is scared for seeing the clone of her former boss, for if he saw her, he might know her and will skin her to utilize his silk suits. They wanted to leave, but they are seeing that Krew is on a phone, and talking to someone, Taylor wanted to stay to find out who is behind making this clone. Krew was then saying on the phone, "I don't know why you want me to take this stone, it looks so ordinary, eh" he stopped talking, listened to his caller, then continued, "It is more than just a stone, if it is a powerful gem, who then donated it to the museum?" he listened to his caller, and was shocked, and replied, "You did for safe keeping, well why do you need me to get it, eh?" He listened to his caller, and responded, "So that's why, well if I didn't want a thief to take my stuff, I would have kept it with me, anyway, I am going to take it I'll see you when I give it to you at your castle," Krew hung up, dialed the combo, the glass opened, and took the gem. Taylor smiled, and signaled Tess to leave the air vent, and be back on the roof.

Taylor looked down, and saw no guards, so she and Tess climbed down by the windows, and was heading for the lamp post, when they heard a crash. That crash was a signal for Taylor and Tess to run now Krew knows that the Dark Diamond he has is a fake. Taylor was back at the lamp post, and wait for Qwark, she soon saw a some lights, it came closer, then saw it was an SUV, Qwark, opened the passenger seat, and said, "Get in," she and Tess obeyed, and Qwark began driving away.
