To spare you the trouble of too much backstory questions, here it is (from the RPG entry):
Backstory
One thousand years ago, the Toa Nuva fought their final battle against the Brotherhood of Makuta in Karda Nui, the Universe Core, the World That Feeds Worlds. While there they battled Makuta, Shadow Matoran, and found the secret of waking Mata-Nui. Takanuva, partially drained of light, and the Kanohi Ignika, spawning itself a body, joined the battle.
The battles were long, epic, and inconclusive, but, that was about to change.
The Toa Hagah located Makuta Teridax and attempted to destroy him. He had one final trick though. His plans had failed, he hadn't expected the Order of Mata Nui to rise up, and with his Brotherhood being destroyed by the Order, and his Karda Nui team wiped out and dying, thanks greatly to the Ignika, he made one last move.
Using all of the power he could, drawing on the power of the legendary location, he vanished.
As the Nuva once more entered the Codrex, but Artakha had spirited away Takanuva who seemed to want the freedom of the Av-Matoran more than anyone.
Artakha knew of Vican's findings, and used a Klakk to cure Takanuva, just to test it out, and was about to send more to Karda-Nui, or bring the Av-Matoran to his realm for healing, but, everything changed the moment the Toa of Light was gone.
The Ignika was blindsided by power. Chirox's body had risen up and fired plasma at the Toa of Life, and rendered him unconscious.
Before the Nuva knew what was happening the body fell and the essence of a Makuta left. Screeching to the Nuva's minds, it yelled "I am Teridax!". The Nuva recognized the voice and immediately readied for a strike.
Before they could act, Teridax struck.
He tore their minds apart with all the energy he could muster, leaving only fragments and strips of the Nuva's minds intact. He then set about his new plan.
He used the last of his energy to heal their minds.
But this wasn't a good thing. The Nuva's minds were healed by Teridax, and he wanted only one thing, vengeance.
The Nuva were now under the influence of their new states of mind, the darkness Teridax had implanted drove the Nuva away from Karda-Nui as the Klakk arrived to heal the Av-Matoran, and they didn't look back. Instead they went out, conquering lands, and became rulers, just as Teridax had wanted.
Takanuva was still in Artakha when he learned, but due to this, and the extra affects of his Klakk's attack since his barrier wasn't a full one, he changed. He developed a strictly black and white sense of justice and went out as a wanderer, persecuting and executing anyone he viewed as "black".
The Destiny War was coming to an end with the Order winning. Almost every member and servant, everyone on the Orders side, was nearly dead. Only Brutaka, Umbra, Krakua, Mazeka, Helryx, Axonn, Trinuma a few other agents and some Mana-Ko and Maxilos survived. The Dark Hunters, though allied with the Order, saw their chance, and struck, blindsiding the remains of the Order.
The end result was mutual destruction of both sides, the survivors include Brutaka, Umbra, Krakua, Mazeka, Helryx, Mana-Ko, and Maxilos robots while the only surviving Dark Hunters are Lariska, The Shadowed One, Lurker, Gladiator, Firedracax and few others.
Current Story
One thousand years later, once the Nuva have nearly succeeded in conquering the world, with the exception of Metru-Nui due to its importance, there is little left for anyone to live for.
The Dark Hunters were nearly slaughtered again by Kopaka's army who they attacked. They were outmatched by his tactical brilliance and now only Lariska, The Shadowed One and Lurker remain.
Helryx now, on Metru-Nui, which is led by Turaga Dume and Vahki, use the city as a refuge for those who have nowhere else to go. This includes Skakdi, Toa, Matoran and Turaga of other elements (ie. Sonics, Plantlife, Gravity, Iron, etc.) and various other species.
Helryx, along with the Dark Hunter survivors and Order survivors along with other Toa, Skakdi, Turaga and more now make up a secret underground resistance. They gather allies on Metru-Nui who haven't lost their will to fight, along with Bohrok which they repair, Maxilos which can be repaired, Exo-Toa which they can repair, Toa on the city like Tamaru and Kopeke and other elemental types, and are preparing to liberate the world.
Helryx hadn't lost faith in the Nuva However, and went to see Gali in her Kingdom.
Outraged, Gali, in perfect Adaptive Armor suited to her watery kingdom, easily slew Helryx who managed to send a message back to base saying "They are too strong in their own kingdoms. Our powers are beneath theirs there.", referring to the Adaptive Armor.
Now, Krakua leads the Resistance as they prepare to launch an attack on the Kingdoms, starting with Lewa on what was formerly Xia. Though each Toa has an army of their own elemental type Toa, along with Matoran and Turaga living in their Kingdoms, the Resistance has decided to strike, even though there is also the threat of Takanuva around, who still wanders, killing anyone "black".
You chose your side and try to wage war on the other while fulfilling your mission. The Empires want Metru-Nui, but can't risk an attack in case its destroyed, while the Resistance wants the destroy the Empires.
And by the way, who is this great artisan you refered to in the latest chapter.
