Children of the Mountain is a religious movement previously headed by Darius Fontaine who lost it in a legal battle with Brother Adrian. It is also the subject of an optional side-mission for Franklin Clinton in Grand Theft Auto V that is completed using the in-game Internet.
When playing as Franklin Clinton, after the mission The Merryweather Heist, he will receive a text from Brother Adrian, asking him to go to their website, to complete the four stages of the C.o.M process. However, the first stage can be achieved by visiting the website earlier and initiating the first stage.
|The player will need to answer a multiple choice test. Regardless of which answers the player chooses, the result will always be the same; It will say that Franklin is frustrated with his life and that he needs to find a purpose in his life and a deeper understanding about himself. After this, the player will need to wait some in-game hours to receive a password via e-mail to continue the test. The password will always be FUTILITY; Once the player receive it, he needs to go to the link on the e-mail and write the password to conclude the first stage of the C.o.M process.|
|To complete the second stage, it will be necessary to donate $199 dollars to the cult. Once the player donate it, he will need to resolve a puzzle consisting of forming words with the letters that are presented, once the words are formed a letter is added to a phrase on the bottom of the page. The player needs to complete the phrase in less than one minute. The eleven words are: Divine, Completeness, Orthodoxy, Process, Realization, Awareness, Actuality, Denial, Perception, Interpretation and Potential.
It is impossible, however, to complete the puzzle in one minute (the completed phrase is "you are an idiot"). Once the time expires, regardless of how many words were found, the second stage will be completed.
|To continue to the third stage, the player will need to donate $4,999 dollars to the cult. The third stage consists of a slide show that the player need to watch until the end. Click on the link at the bottom of the page in the last slide to complete to continue. Wait a couple of minutes to receive a new e-mail with a new password (ACTUALITY) to write on the website and conclude the third stage.|
|To continue the player will need to do a new donation to the cult, this time of $9,999 dollars. The fourth stage consists of a new test, but now the player can only answer "Yes" or "No". Select "Yes" for all questions to complete the last stage and receive his certificate of completion of the C.o.M process.
After this, Franklin will receive a last e-mail from Brother Adrian, indicating that a Children of the Mountain T-shirt has been delivered to his wardrobe, which is the reward for completing this side-mission (obtaining the T-shirt therefore costs Franklin $15,197).
It is not explained why Brother Adrian chooses to contact Franklin directly. After completing the four stages and receiving the T-shirt, Adrian indicates that the C.o.M. intend to continue harassing Franklin to take part in further courses, and he will periodically receive further e-mails inviting him to visit the website for further instruction (no more is available, though Franklin is free to donate more money).
The Cultstoppers website mentions Children of the Mountain as a cult similar to Epsilon and several people in the state of San Andreas also share this confusion in which members reply that Children of the Mountain is not a religion.
