Krilessh is one of the many popular myths related to the myth group, Mental Assistance Department. He is another immortal being that was used as a possible cure for mortality by the Department's doctor. Krilessh lives in an ocean with an important monarch on the island in the middle, containing many containers of what appears to be failed experiments.

Biography

Krilessh was a sailor who ended up crashing his boat into an underwater Mindwalker base. This caused them to capture Krilessh and experiment on him, causing him to forget most of his past life and affecting a lot of his sanity. Along with this, he became immortal and the Mindwalkers then set him free in order to see the potential long-term side effects of the experiments.  After being released by the tower, Krilessh met Shelly, his lobster and all-powerful friend, and they both resided in the ocean for a long time. He was mostly left alone until he was eventually discovered by Ipiprix and was used as a possible cure for mortality.

After a large series of events including the rise of the Mind Walkers, Immortius would arrive at Castaway with the player where they met Krilessh. At the end of Jalcrl Nwm, Krilessh joined the player, true_faces, Immortius and Cecil_Montgomery in their fight to stop the Mind Walkers. After the victory of the player over them, he says that Shelly mentioned he wasn't monitored anymore, relating to the fact the Mindwalkers aren't watching him as a test subject anymore, now defeated.

History

Krilessh created his account on 5/4/2019, and created Castaway the next day. There is not much other known history involving Krilessh. There was an investigation report produced by user, xlgamerlx, a former special agent for the Roblox's Myths Intelligence Agency, on July 23rd, 2021. It consisted of Krilessh's basic profile details, and investigative findings from "Castaway". Furthermore, this user recorded an interaction of Krilessh with numerous hunters at his game.

Appearance

Krilessh’s current outfit consists of the “Torn” shirt and pants, the “Privateer” hat, and the “Walk The Plank You Scurvy Dogs!” face to complete his pirate-like theme.

Personality and Traits

Krilessh is confusing and illogical, almost unintelligent. Any communication with him will be difficult, as he always brings the topics of conversation back to Shelly or something pointless. He is friendly, however, and will always be willing to chat or give tours of the island and the ocean to visitors.

Abilities

Krilessh has the ability known as immortality, meaning that he can not be killed. His immortality is a result of the experiments the Mindwalkers performed on him, which severely affected his mind, causing notably memory loss and the inability to realize the passage of time: he thinks he's only been here for a few years, when probably hundreds of years have passed since his arrival on the island. Krilessh also has really good swimming capabilities, due to the time he spent in a marine environment.

Game

Castaway

Main article: Castaway

Castaway features the Mind Walker probe hiding under a natural island. The cave system that resides below it leads to five terminals, each pertaining to a specific object. The terminals are reached by going through small holes that open up into a bigger area. There are six holes, one for each terminal, and one for the code to be inputted after all the terminals are found and clicked. Inputting the code correctly will open the large vault door located in the middle of the island. Entering the vault will open up into the midsection of the probe, where many lifeforms used for mind walker experiments are found.

Group

Mental Assistance Department

The Mental Assistance Department is the myth that Krilessh is involved in and his game is a core part of it. He is ranked as “Cures” in the group.

Relationships

Shelly

Shelly is Krilessh’s loyal companion who he takes with anywhere. Krilessh says that Shelly often talks to him, which could be either a result of the experience on Krilessh’s mind, or hint that Shelly is just special. After Jalcrl Nwm, Shelly supposedly told him “not being monitored anymore”.

Mind_Walkers

Mind Walkers are the creatures that experimented on Krilessh when he crashed his ship, resulting in him not knowing much of his own history, being immortal, and other side effects. He eventually helped fight them in a way alongside the player.
