How do you start and finish Children of the Mountain in GTA 5?

Children of the Mountain is Franklin-only optional content, and it is much less like a normal GTA mission than most players expect. After The Merryweather Heist, keep an eye on Franklin's phone for a message from Brother Adrian, then open the linked site through the in-game browser. You can also find the group's page yourself if you know where to look. The first test costs nothing, but don't overthink the answers. The cult gives Franklin the same vague diagnosis whatever he picks: he's lost, frustrated, and supposedly in need of guidance. An email then gives you the first password, FUTILITY. If you're short on cash and would rather save your story earnings for vehicles, weapons, or property, it makes sense to think twice before using buy GTA 5 Money services just for this side activity, because the cult doesn't pay anything back. Stage two costs $199 and sends Franklin into a timed word game. The answers include Divine, Completeness, Orthodoxy, Process, Realization, Awareness, Actuality, Denial, Perception, Interpretation, and Potential. You don't actually need to solve them all. When the timer runs out, the process carries on anyway. After paying $4,999, watch the slideshow and wait for the next email password: ACTUALITY. The last payment is $9,999. Say "Yes" to every question, receive the certificate, and the cult shirt will turn up in Franklin's wardrobe.

Is Children of the Mountain worth completing in GTA 5?

Not if you're expecting money, a secret robbery, or a hidden mission chain. The whole thing costs $15,197, and the practical reward is just a T-shirt. It doesn't count towards GTA 5's official 100% checklist either. That's kind of the point. You keep paying because the game makes it feel as though there must be something bigger waiting behind the next email or password. There isn't. The word puzzle is the clearest joke: it looks like a test of intelligence, but your performance changes nothing. By the end, Franklin's "personal growth" has been reduced to agreeing with every prompt. The cult's name also confuses some people. It has nothing to do with hidden child NPCs or a secret settlement in the hills. "Children" means followers of the organisation. For players comparing unusual save setups or browsing GTA 5 Modded Accounts, this is still a small Franklin-only curiosity rather than a major unlock. Complete it for the shirt, the joke, and the weird emails. Skip it if you'd rather keep the cash, because the cult's real reward is making you realise you've just paid a fortune for a logo on a T-shirt.
