Step inside Dok-Ondar’s Den of Antiquities at Star Wars: Galaxy’s Edge in Disneyland and you’ll find legacy lightsabers inside glass cases, a wooly Wampa lurking in the rafters and a hammerhead alien shopkeeper counting his galactic credits from his lofty perch.

But watch your step. You don’t want to mess with Dok. Or get on his bad side. Assuming he has a good side.

“Dok-Ondar is a force to be reckoned with,” said Walt Disney Imagineering managing story editor Margaret Kerrison. “He may be 245 years old, but he’s not feeble. He’s been around and he’s very well connected. He’s a very dangerous guy.”

Dok’s Den will be the best place to find intergalactic black market goods in the Black Spire Outpost village on the “Star Wars” planet of Batuu, the setting for the new 14-acre themed land coming to Disneyland.

The antiquities shop will sell Jedi and Sith artifacts along with one-of-a-kind treasures from different eras of the Star Wars galaxy. The shop will carry pre-built legacy lightsabers associated with “Star Wars” characters such as Shaak Ti and Ahsoka Tano.

Concept art of the Den of Antiquities shows a shadowy shop filled with taxidermied extraterrestrials, skeletal remains of winged space creatures hanging from the domed ceiling and tentacled sea aliens floating in glowing glass cylinders. An upper balcony will be stuffed with souvenir spoils collected from throughout the Star Wars galaxy.

“He has such a large collection that everyone actually knows him,” said Imagineering creative producer Brian Loo. “He no longer has to travel because all his clients come to him instead.”

The play on words between “den of antiquities” and “den of iniquities” is no casual oversight. The mysterious Ithorian collector and trader with eyes bulging from the side of his hammerhead and two mouths in his curved neck traffics in illegal interstellar goods.

“We knew that we wanted to meet an Ithorian in our land,” Kerrison said. “We just fell in love with him from the beginning because his story is that he is the gatekeeper of the black market.”

During a recent construction tour, plastic sheeting covered props arrayed on the upper level of Dok’s shop.

“When this is done, it just gets completely filled out on the upper level,” said Imagineering executive creative director Chris Beatty. “This is all props on the upper level. You can’t even shop the upper level. There’s even a 12-foot taxidermied Wampa that’s in here.”

Shoppers will be able to peruse merchandise on the lower level under the watchful eye of Dok. Every item in the shop has a story, with some stories more dangerous than others, according to StarWars.com.

An audio-animatronic Dok will tend to his financial ledgers, answer calls and survey his inventory while sitting at an elevated perch in his shop. Throughout the workday, Dok may grow angry when he gets a call from somebody trying to rip him off. Counting his galactic credits or looking over a bookkeeping ledger could brighten his mood.

Customers can barter with Dok over the price of merchandise with the help of a Disney employee.

“He’s always diligent as to what’s going on within the shop, counting his money, making sure that nothing has been taken or missing in his collection,” Beatty says. “When you go to buy something, you can interact with him from time to time.”

But don’t expect a discount from Dok. You may end up walking away paying more rather than less after haggling with the tough businessman.

“I’ve never known him to give a deal,” Beatty said.

But if the price is right, Dok will be willing to trade anything from his collection, according to Imagineers.

A recent tour of the Walt Disney Imagineering animation building in Glendale showed off a Dok-Ondar animatronic figure in action.

Imagineering show programmer Amy Goodwin peppered Dok with questions.

“Hey Dok, he thinks you’re overcharging,” Goodwin told the animatronic shopkeeper. “Can you give him a discount?”

The surly creature responded in an alien tongue, the lips along his two mouths moving as he spoke.

“OK, I’ll tell him to go away,” Goodwin said.

While most visitors won’t understand what Dok is saying, they will be able to discern two distinct moods: happy or frustrated.

“Storywise he always has a reason to switch between them,” Goodwin said. “He never randomly goes from happy to frustrated. There’s always a reason for it.”

Dok’s seemingly-randomized responses are built out of blocks of animation clips that combine into a playlist of short scenes.

“It’s not pulling at random, but it still gives that feeling of randomness,” Goodwin said. “If you sit there and watch, there’s never going to be an hour that’s exactly the same as any other hour that he runs because of how he transfers between these little scenes that he has.”

Dok-Ondar’s Den of Antiquities opens in Star Wars: Galaxy’s Edge on May 31 at Disneyland and Aug. 29 at Disney’s Hollywood Studios in Florida.
