I was a fool.— Immortius
Immortius is a myth related to the events happening in the Mental Assistance Department. He is the last of the Nephilim, which are immortal and giant beings. The player first meets him in the game In Ruina Eius de Nephilim where he's seen in the last room rotting in chains due to killing the every other Nephilim and their chief, his own father.

Biography

When Immortius was younger and curious, he stumbled upon a tower that fell from the sky long before man existed. When he drew near, it began to speak to him, promising wonderful things that consisted of power, status, wealth, and more. In return, the tower manipulated him into killing all Nephilim, including his own father, the Chief. The entities that manipulated him, known as Mindwalkers, had a purpose in this killing: highly resistant to Mindwalkers control, the Nephilim could have posed a threat, and needed to be eliminated. However, only a Nephilim could kill a Nephilim. When he was the last, the tower subdued Immortius and put him in chains left to rot.

Thousands of years later, a civilization stumbled across Immortius’s prison and set up several puzzles that symbolize his past to keep others from reaching him. Though the riddles were difficult, it didn’t stop three doctors from figuring it out. Their goal was to extract the beast’s eye and blood to figure out what gives Nephilim immortality.

Found in the Mental Assistance Department’s basement, the eye could be returned to Immortius after obtaining the “A L L” badge. Once a player returns the eye, the language barrier is broken as Latin turns into English. He is also freed from his eons of shackles, allowing him to get revenge on the tower of liars in Krilessh’s game, “Castaway''. He would then return to his human form and join Cecil_Montgomery, true_faces, and the player on a boat trip to “Jalcrl Nwm”. Here, he would turn back into his Nephilim form and fight off a lot of Mind Walkers.

History

Immortius created his account on 4/6/2019, and made, In Ruina Eius de Nephilim, a day later. Not much else history is known about him. On May 16th, 2020, a former agent from the Roblox's Myths Intelligence Agency had written an investigation report on Immortius. Their name was purelabs and the report detailed their findings within "In Ruina de Nephilim". Additionally, Immortius was interrogated by other agents on August 13th, 2021. These agents were xlgamerlx, xXWinnterNightXx, Scoterbium, and nicosela6.

Appearance

Suited up in all-metal armor, Immortius’ smaller form consists of dark yellow skin, “Warriors” shirt and pants,  the “Roman Warrior” helmet, a t-shirt of the “Eye of Immortius”, and the “Zombie Face'”. His Nephilim form is a giant black beastly figure with sharp teeth and a weird design atop his head.

Personality and Traits

Immortius seems to be fairly sane, though he was manipulated into killing an entire civilization, including his father. Spending time alone for millions of years is probably enough to figure out yourself, but on the other hand, guilt and revenge might’ve consumed him being chained for eons, thus an underlying mental disorder possibly exists.

Abilities

Immortius is immortal, a common ability shared among the Nephilim. However, this longevity had consequences, as he would be chained up for eons after killing the rest of his kind, leaving nobody to reach him for a very long time.  

His eye gives him strength,  and the ability to ‘project’ himself in his smaller form. Even chained, he was able to create this other form, permitting him to see and wander around the world.

Game

In Ruina Eius de Nephilim

Main article: In Ruina Eius de Nephilim

In Ruina Eius de Nephilim takes place in some ruins in the desert where many puzzles and secrets reside. At the end, Immortius can be discovered and with the returning of his eye, he can break free of the place he was trapped.

Group

Mental Assistance Department (Group)

Immortius is ranked “Cure” in the group. This is because the doctors of the department found him and took his blood and eye as a hope for immortality. This would be “Cure #4” which would be a failure.

Relationships

Mind_Walkers

Mind_Walkers are the spiders that manipulated Immortius in the Tower of Liars. They also are the ones that trapped him in chains after having promised him things such as power and wealth. Once Immortius was freed, he would seek revenge against them, which he fulfilled.

Ipiprix

Ipiprix is one of the doctors who discovered Immortius and took his eye. He hoped that it would lead to immortality, but this would ultimately fail.
