The holographic map or simply holomap was a holographic device that displayed a model of a steampunk-style city created by using two birthday gifts given to Helen Magnus by her father Gregory Magnus for her twenty-sixth and thirty-fourth birthdays.

History

	The holographic city. Episode 3x02 - "Firewall": Two weeks after Will Zimmerman died and visited the spirit realm during the Big Bertha crisis, a male/female pair of tabors infiltrate the Old City Sanctuary. They brought along with them a spiderbot with the goal of using it to access Will's memories. While the tabors themselves were ultimately unsuccessful in their effort, their attempt inspired the Sanctuary team to use the spiderbot themselves to retrieve Will's hidden memories. In these memories it is revealed that during Will's time in the spirit realm, he was visited by Gregory Magnus in the avatar chamber. During their interaction, Gregory passed on branded clues that helped Helen Magnus to find the items necessary to bring together to get the hologram to work.
	Episode 3x06 - "Animus": After bringing Nikola Tesla into the fold, Helen Magnus and Tesla spend six days futilely staring at the holographic map, failing to make any real progress until they noticed three turnable rods. After turning the rods, it opened a new interactive screen. Magnus advised caution, as it the screen seemed to be flashing for the input of a password. Tesla however disregarded her advisement and randomly hit several symbols without thought. This caused the holomap to blast the Old City Sanctuary with a defensive EM pulse. On the seventh day, Magnus and Tesla were able to crack the password to this outer security layer of the holomap, which turned out to be an advanced computer system. The system then locked them out when it preformed an automated scan and discovered source blood remnants in their bodies. This caused the holomap to respond with the creation of a particle accelerator that used electromagnets to reach sufficient power that would destroy both them and the Sanctuary. Luckily, they were able to circumvent this deadly issue with an EM field created by Tesla that blocked the scan. Once passed this security measure, during further investigation they accidentally stumble across causing the holomap to display a holographic representation of a hollow planet Earth by saying "Kha harag" ("gateway").
	Episode 3x07 - "Breach": Several unknown amount of weeks later after first learning of the holographic map, Adam Worth tracks down Helen Magnus, luring her to an abandoned warehouse somewhere out in Old City. He traps her inside the decommissioned building with a form of time-dilation using several time nodes that he stole from Praxis. During this encounter, it is revealed that it was Worth who sent the tabors to the Sanctuary. He wanted to gain access to Magnus's holomap as it was the only way to find keystones, an item needed to get to the underground city.
	Episode 3x08 - "For King and Country": Work on trying to further access information in the holographic map is put on hold when the Sanctuary team learns of Helen Magnus's failing health. During this time, they squabble over the idea of letting Adam Worth access the holomap.
	Episode 3x09 - "Vigilante": Adam Worth is finally granted access to the holographic map, in which he helps the team locate a keystone. While Helen Magnus and John Druitt globe trot to collect the keystone, Nikola Tesla is left with the holomap in order to test his new source blood shield. Eventually Magnus and Druitt return with a real keystone and insert it into the holomap, finding a gateway into Hollow Earth.
	Episode 3x10 - "The Hollow Men": After they had found a way into Hollow Earth, Helen Magnus and her team soon discovered that the hologram was a representation of the city of Praxis. When John Druitt and Nikola Tesla fear something had gone wrong during the mission, they plan a rescue by patching Adam Worth's brain into the holographic map via spiderbot to find a safe location that Druitt could teleport to.
	Episode 3x11 - "Pax Romana": Ranna Seneschal interrogates Helen Magnus about being in Hollow Earth and her connection to Adam Worth. Magnus defends herself, saying that Worth nearly killed her trying to access the holographic map and that her father Gregory Magnus broke their laws to warn her about what Worth was coming after her for. Later, Gregory repeats this to Ranna about his need to let Magnus know that she possessed the holomap.
	Episode 3x16 - "Awakening": A mission to investigate an old Praxian fort in East Africa goes awry. In order to save Nikola Tesla's life from the vampire queen Afina, Helen Magnus bartered the holographic map in exchange for their escape. When the queen tried to activate it, the particle accelerator created an explosion resulting in a mushroom cloud reminiscent of a small tactical nuke. Based on the massive crater left behind, it is easily assumed that the blast killed Afina and all of her court still lying in stasis; the last of the vampires. Tesla complains that they barely downloaded a fraction of the data found on the map.

Notes

• Trivia: Even though normal holographic models are a simple projection of light, the Praxian holographic technology was able to be physically interacted with by the touch of one's hands. Standing in and anywhere amoungst the model also didn't cause shadows to form that would have blocked viewing of parts of the city behind them; not causing that part of the model to temporarily disappear until the obstruction moved to allow it to reappear.
  • Based on Helen Magnus commenting on her father Gregory Magnus's fascination with the power and potential technological application of crystals, the physical form the map displayed may actually be comprised of crystal particles created/expelled from the map device. This is supported by the "crystal" sound heard during the device's building of the holographic representation of the city of Praxis.
