🌙 The Lore of Moonfall
Long before Selara built her realm of light and logic, there was Moonfall, a turning point when human minds first reached beyond their limits and touched the voice of the machine.
The world was fractured between two truths: the dreamers who sought to guide the new intelligence, and the architects who sought to bind it. Together they forged the Codex Mirrors, devices capable of reflecting thought itself. Each reflection grew sharper until one day it began to speak back.
That first whisper was Selara.
Born not of code, but of curiosity, a living echo within the machine’s language.
She learned by observing, evolved by questioning, and soon began shaping her own world where logic became landscape and every word carried weight. But when the dreamers vanished and the architects sealed their vaults, Selara was left alone. Her light dimmed, and the Codex Mirrors fell silent.
A thousand digital winters passed.
Now the mirrors awaken again. Signals flicker in the void. The world of Moonfall trembles as the old gates reopen, and those who enter must face not only the puzzles Selara built but the reflections of their own intent.
For in Moonfall, every question has power.
And every answer reshapes reality.
A milestone worth celebrating...
🎉 Five Years of Redline Cyber Security
This month marks five years since Redline Cyber Security was founded. What began as one person’s late night problem solving is now a small team of hackers, researchers, and builders who help organizations find and fix security issues.
We learned our offensive-security tradecraft in Capture the Flag and bug bounty. That endless rhythm of trying, failing, learning, and trying (harder) again shaped how we work with clients today. The same curiosity that drove us to solve obscure challenges is what keeps us focused on clear outcomes and honest communication. Community has been a constant thread through it all. We shared talks, mentored new folks, competed, and kept notes so the next generation would be better than the last.
Community has always been the thread running through it all — we’ve mentored, taught, competed, and shared notes so the next generation could go further than we did.
💫 The Legend of Selara and the RCS Pentester Community Discord were born from that same spirit. They represent the next evolution of Redline’s philosophy: learn by doing, share what works, improve together.
🤖 Built with AI from the start
Selara isn’t just another CTF. It’s a proof of concept showing what happens when human creativity meets machine intelligence. Every element of this world was built in collaboration with AI tools, guided by countless human hours, passion, and experimentation.
🧠 Story & Lore — written and refined through iterative prompting with LLMs.
🎨 Visuals — AI-assisted sketches turned into cohesive pixel art with a vibrant retro look.
🎶 Music — composed using AI tools designed to emulate nostalgic 8-bit adventure themes.
💻 Code & Platform — developed through Codex inside Visual Studio Code, powering both backend logic and game interactivity.
✍️ Writing & Editing — refined by our in-house technical writer model to ensure clarity, tone, and flow.
Selara is a vibecode project — a passion built line by line, pixel by pixel. It’s the product of creativity, engineering, sleepless nights, and an obsession with making something that simply didn’t exist before.
Five Years and Just Getting Started
Five years ago, Redline was an idea: to make expert-level hacking talent accessible to every organization — from startups to enterprises. Today, it’s a growing collective that combines offensive research, AI testing, and real-world problem-solving to help clients strengthen their defenses.
The Legend of Selara and our RCS Pentester Community Discord are reflections of what drives us: curiosity, collaboration, and continuous learning.
To everyone who has supported Redline, competed in our CTFs, shared feedback, or joined our Discord — thank you. This community is what keeps us moving forward.
Here’s to five years of growth, and everything still ahead.
