South of the Monastery of Spinjitzu, Ignacia is the homeland of Kai and Nya. It is located on a rocky hillside, surrounded by trees and shrubs. A stone path outlines the entrance of each home, and a tall water tower is located next to the local Four Weapons Blacksmith shop.
Supposedly, there was a battle long ago near Four Weapons, before Garmadon turned evil, and Ray fought alongside the two brothers. It seems that when Samukai says that he wanted revenge on Garmadon from turning against him, he was referring to this incident.
Sometime after this, around the time that Nya was three and Kai was five, Krux (who was disguised as Dr. Saunders) threatened Ray and Maya and said that if they didn't work for him and build armor for his army, he would go after their kids. While their parents were lead away by Krux, Kai and Nya played in the front of the blacksmith shop.
Master Wu returned to Ignacia in search of the blacksmith's son, Kai, and left disappointed in Kai's arrogance. Mere minutes later, Ignacia fell under attack by Samukai and his skeleton army. Nuckal and Kruncha trashed Four Weapons looking for the map to the Golden Weapons while Wu returned and fought Samukai, resulting in the destruction of the water tower. Nya was kidnapped during the battle, and Kai left with Master Wu to train in the ways of the Ninja.
Nya returned to the village after being rescued, and when the Ninja returned, the residents of Ignacia celebrated.
Garmadon and Wu end up in Ignacia after returning from the Realm of Madness, after arriving Garmadon says to the Rice Farmers that he is back.
Lord Garmadon used his Mega Weapon to go back in time to keep Nya from being kidnapped, thus preventing the Ninja from becoming united. The Present Ninja went back in time to tell Past Master Wu what happened so that he could help them stop Lord Garmadon. When the Bone Fist misses, Samukai orders a retreat and takes the Skull Truck back down the road with the other skeletons. Master Wu tries convincing Kai to become a ninja so that the future will be saved, but he doesn't want to go. Finally, Nya says she wants to become a ninja, and Kai goes only because she wants to. The Ninja follow along to make sure he becomes one of them and unlocks the fire inside.
During the Day of the Departed, Kai and Nya visited their parents old blacksmith shop to light a lantern in memory of their parents, who at the time were assumed deceased.
Soon after, Chen showed up after being revived by the Departed Blades and attacked Kai and Nya with a smaller version of his army of Anacondrai. Chen is defeated, and Kai and Nya leave to meet the others at the museum.
Kai returns to the blacksmith shop where he grew up to find answers about the Vermillion armor he found, and finds a secret basement when he strikes a gong, and finds it filled with other Vermillion armor, and the Dragon Blade.
