Lord Garmadon's Dark Fortress is a location in LEGO Ninjago: Masters of Spinjitzu. It is a tower built by Lord Garmadon in the Underworld, which served as the villain's main base of operations after becoming King of the Underworld.
Samukai arrived in the Dark Fortress to inform Lord Garmadon of the Ninjas' progress by learning Spinjitzu and obtaining the Scythe of Quakes. The Skulkin General thought he had failed, but Lord Garmadon was pleased with the information, going on to tell Samukai that everything was according to plan.
Upon falling into the Underworld, Master Wu traveled to the Dark Fortress where he was greeted by Lord Garmadon. As Master Wu drew the Sword of Fire, Lord Garmadon sent a small group of Skulkin to attack Master Wu—though the effort was fruitless as he quickly fended them off using Spinjitzu.
The villain then sent Samukai out to fight. Master Wu tried his best to keep up with the battle, but he was at a disadvantage thanks to the Golden Weapons that Samukai had used. Lord Garmadon commanded the Skulkin General to hand over the Weapons, but Samukai disobeyed Lord Garmadon's orders and grabbed it for himself. However, because all four weapons were too powerful to wield at once, Samukai disintegrated, which created a vortex for Lord Garmadon to escape through.
As the portal lingered, Lord Garmadon said his goodbyes to the group of Ninja before walking inside, leaving the Golden Weapons behind and ultimately abandoning the fortress.
Wu and P.I.X.A.L. tries to open a portal to the Never-Realm. But the Traveler's Tea wasn't strong enough. At one point, a portal to the Underworld was opened, revealing the Skulkin, their vehicles, and the fortress.
