Upon reaching the HQ of the Blade of Marmora, it is located in a safe spot between two black holes and a blue Supergiant star. Keith and Shiro travel to their base in an effort to align with the Blade of Marmora led by Kolivan and his lieutenant Antok. But Keith's possession of one of their blades causes immediate friction with the Trials of Marmora to resolve them one of two results: knowledge or death. Keith must fight to unlock about his past, and with each fight exhausts himself more and more. When entering a vision of his old home with his father, the outside of the house shows a Galra invasion, giving Keith a choice: stay and learn, or leave and rescue. The Red Lion attacks the base sensing Keith's endangerment, and upon deciding to end this mistrust and gain their alliance, Keith relents his dagger, only for it to awaken its true form of a saber upon his enlightened decision and revealing a truth: Keith has part Galra ancestry. Meanwhile, Commander Thace (the Marmora spy who shutdown the Solar Shield) alerts the Order that the investigation is increasing and the timetable must escalate to now!
For millennia, the evil Galra Empire has plagued the universe by conquering planets and destroying their inhabitants. The only known threat to the empire's power and plans, is the legendary "Defender of the Universe" Voltron, a 100 meter tall robot warrior composed of five lion mechas whose whereabouts are presumed to be unknown. The Galra Empire's path of conquest and search for Voltron has led them to Earth's solar system. A group of space pilots-Shiro, Keith, Lance, Pidge, and Hunk-discover the blue lion and immediately get swept up into the Galran War. They meet Princess Allura, become the next Paladins, and reunite the five lions to form Voltron and free the universe from the Galra Empire.
**NOTE: Even though Netflix releases all episodes of Voltron: Legendary Defender on one day, they are portrayed on the TV Calendar as airing one episode a day, for ease of visualisation.
