Londark (spelled Londarg in the Yen Press translation), also known as Londark of Gray Steel, is an Elf Sorcerer and he was a former member of Brigandia, where he acted as Demiqas' right-hand man up until the guild lost control of Susukino to Silver Sword.
He appears to be well versed in the games mechanics as he recognizes the perks and weaknesses of the Swashbuckler and Guardian classes almost immediately. Shiroe claims that Londark was more powerful than Demiqas for obtaining a rare drop from the Fire Lizard's Cave, although that may have been to simply rile Demiqas up.
In real life, his name is Ace Satou (佐藤瑛磨 Satou Esu), a 19-year-old part-time leader.
Londark wears a long gray and yellow robe that covers his feet and sprawls across the ground. He wears his hood up while his hair covers half of his stone-cold face. He has pointed elf ears.
Not much is known about Londark's personality other than that he shows little of it. He appears to be loyal to Demikas and/or his Guild and puts great faith in Demikas's judgement when fighting Nyanta. Even when Demikas is left with one point of health, Londark refuses to back down despite the battle being decided.
Still, after Demiqas' defeat, Londark appeared to have lost faith in his guild master and left Briganida, and eventually joining Plant Hwyaden. When he was confronted by Nyanta who berated him for helping to bring about war, Londark expressed no remorse and simply told Nyanta to take it up with his Lander employers, and then revealed his animosity in how he feels trapped in this new world and is denied even death to be freed of it.
Prior to the CatastropheEdit
In the real world, Londark is a 19-year-old part-time leader named Satou Esu.
Saving Serara arcEdit
Londark makes his first appearance outside the walls of Susukino, where Brigandia had looted some caravans. He comments that since PKing only results in the player teleporting to the Cathedral, PKing wasn't a big deal. He then reports to Demiqas that while he has sent several men on the search for them, they had not yet found Serara or Nyanta.
He later accompanies Demiqas in his attempt to capture Serara. While Demiqas and Nyanta fight, he spends the majority of it watching and making observations on both Nyanta and Naotsugu. When Demiqas falls, he refuses to back down and orders the healers to replenish their Guild Master's health while attempting to cast a Fireball spell. Before they can do so, he along with the rest of the Brigandia sorcerers are assassinated by Akatsuki.
Gold of the Kunie arcEdit
Route 43 arcEdit
Londark leaves Minami in search of Nureha, who suddenly disappeared; unbeknownst to the Ten-Seat Conference members and their aides, she had taken on her Dariella disguise and joined Tohya's Party on its quest to acquire Dazaneg's Magic Bag while following the Odyssea Knights.
When one of Minami's Ten Seats, the Lander general Mizufa Trude, goes on a rampage in hopes of inciting war between the Eastal League of Free Cities and the Holy Empire Westelande, Londark encounters Nyanta. Although Londark apologizes for the incident in Susukino, he adamantly saw Landers as disposable figures that were none of his concern. He and Nyanta engage in discussion, with Londark still bitter over the Catastrophe and unwilling to change his viewpoint of the world. As Nyanta realizes that it is futile to reason with Londark, Mizufa stabs the Sorcerer through the throat from behind. As he dies and is sent to the Cathedral, she comments that being an Adventurer, capable of dying as many times as you want and reviving every time, must be wonderful.
- In the light novel and manga, Shiroe beheads Londark after Akatsuki cuts Londark's (likely casting) arm off.
- The Japanese version light novel accidentally states that Demiqas was beheaded, even though Demiqas was already dead at that point. This error was never fixed in subsequent translations, so every edition of the light novel says that.
