Luther

Luther is one of Lin Sanjiu's first Posthuman companions in the novel. They met in her homeworld Hyperthermal Hell at the start of its apocalypse.

He is always found alongside Marcie, who is not a real posthuman but the first of his many personalities given form through his evolved ability.

He has several other personalities, including Septimus and 12.

Appearance
He looks to be a Caucasian youth with buck teeth.

Personality
Friendly but naive. Some of his personalities were protective of him and keep the existence of 12 and his actions a secret to protect him.

Powers
Luther has a relatively high growth value of 190 and possesses standard posthuman improvements to strength, adaptability, and resistance as well as the power to let his personalities create their own bodies, called [Persona Separation]. Currently, he has no control over which personality is embodied as Marcie is the only personality able to exist independently. He believes that more personalities will be able to exist independently as his power evolves.
 * Marcie must remain within 20km of Luther or she disappears.


 * Her mortality status is unknown, but it does appear as if she can be killed and be unable to dematerialize by herself.

Story
Luther, along with Marcie, was the first friendly posthuman Lin Sanjiu met during the first day of the apocalypse. After being trapped by Lin Sanjiu as a result of a misunderstanding, they teamed up to escape a duoluozhong. Together they traveled the wasteland before joining the Oasis.

He was replaced by his 'Septimus' personality after getting injured and as part of the process of his ability leveling up. Septimus later betrayed Lin Sanjiu and Marcie, and was eventually revealed to be the secret sociopathic personality, 12. After trying to kill Lin Sanjiu and starting the downfall of Oasis, 12 fled while Lin Sanjiu destroyed the Oasis, forcing Marcie to go along as a result of the 20km distance restriction of his ability.

Lin Sanjiu still considers him a friend but was not able to meet him before she was forced to leave Hyperthermal Hell.
