Heartstone Trollmarket was a subterranean metropolis that is the home of Troll civilization, pulsing with energy and jewel-fueled light, where trolls eat, fight, and down brews in pubs straight out of Viking lore. It is located beneath the town of Arcadia, and the entrance, which can only be opened with a Horngazel, is under the main bridge of the canals.
However, as of "The Eternal Knight: Part 2" after Morgana's defeat and ending the Eternal Night, the Heartstone within Trollmarket has lost all of its power and is therefore uninhabitable, forcing the remaining trolls to venture to New Jersey to find a new Heartstone.
After the Gumm-Gumms were defeated in the Battle of Killahead and trapped in the Darklands, the remaining of the Troll race migrated in search of peace. They stowed away on a ship called the Mayflower, along with several Gnomes for companionship and nourishment. They finally arrived at what is now New Jersey and after much searching, they managed to find a new Heartstone under Arcadia. Thus, they found their new home that would be known as Heartstone Trollmarket.
Part One (Trollhunters)
After Jim Lake was chosen as the new Trollhunter, the Gumm-Gumm Bular went after him to end his life. So, Blinky and AAARRRGGHH!!! took him and Toby to Trollmarket, being the first humans to step on it. Although all the Trolls were reluctant to them, in the end, both were accepted. Trollmarket is frequently visited by them, mainly in the midst of some Trollhunter crisis.
After Bular's death, Claire Nuñez became the third human to reach Trollmarket. After Angor Rot got a Horngazel, he led an army of Golems to invade Trollmarket. With the union of all the Trolls and allies of Jim, Angor Rot was defeated at the end, at the cost of a life of several Trolls, including AAARRRGGHH!!! (who was revived in Part Two).
Part Two (Trollhunters)
After escaping Killhead Bridge, the Troll Tribunal had Jim out on trial for seemingly letting Gunmar out after he went into the Darklands. After Jim is proven guilty, Queen Ursuna was revealed to be behind Gunmar's escape all along and the Gumm-Gumms attacked the metropolis. The Gumm-Gumms started to brainwash Draal and several other trolls to become their slaves. When the Trollhunters managed to get all the remaining trolls to safety, the Gumm-Gumms took over Trollmarket.
Part Three (Trollhunters)
In later episodes of Part Three, it is discovered that Merlin has imprisoned Morgana underneath the Heartstone of Trollmarket. Morgana later uses the Heartstone to keep the Eternal Night active and stable. After the Eternal Night War, the Heartstone within Trollmarket has lost its magic and is therefore rendered uninhabitable for Trolls.
Part Two (3Below)
After learning that Kanjigar the Courageous is the protector of Gaylen's Core, Toby and AAARRRGGHH!!! lead Aja, Krel, and Varvatos to Heartstone Trollmarket to consult the Soothscryer, with Morando not far behind and several Gumm-Gumm zombies mindlessly attacking them. There, the spirit of Kanjigar leads them to Gaylen's Core inside the Deep. However, Morando managed to narrowly steal the core first.
Trollmarket is a great underground metropolis. It is located several meters underground, connected to the entrance by a long bright crystal staircase. It consists mainly of houses, bridges and trading posts arranged around the rock. There are all kinds of minerals and crystals everywhere that provide illumination. In the center is the Heartstone, the source of life and sustenance of all the Trolls.
However, in the aftermath of the Eternal Night War, Trollmarket is now more dark, damp, silent, wrecked, and creepy with what's left of the Heartstone at the center.
