He could feel the minds of those lost—his parents, the missing children, every colonist swallowed by Claire—pressing into him, begging, pleading, screaming. Every memory was a blade cutting into him, and yet he could not break away.

A new presence emerged within Claire: other minds from beyond the moons, ancient and alien, whispering secrets older than Brian could imagine. They sought the same as Claire: dominion, feeding, control. And Claire answered, consuming their essence, learning, growing stronger.

Through it all, Brian glimpsed fragments of his old self—a flicker of anger, a shard of fear, the ghost of his ten-year-old determination. He realized he could influence Claire, however slightly, by embedding his memories as traps, turning his grief and terror into cages. He began shaping parts of the valley, the veins, the whispers, twisting them so that anyone who fell into Claire’s grasp might glimpse the horror before being claimed.

Brian… you can’t stop us…

We are everything…

He whispered back, embedding his defiance into the winds, the dust, the moons. It was a tiny thing, almost meaningless, but it was his.

From the highest cliff of the valley, he watched as Claire’s influence began to stretch toward the colonies on neighbouring moons. Entire settlements vanished in a blink—sucked into impossible folds of reality, leaving behind only faint blue handprints pressed into walls and floors. The sky twisted. Time slowed. The air grew thick, filled with screams of those who were consumed, mixed with the lullabies of children who were never meant to die.

And yet, Brian remained, a flickering ember of self in the heart of the nightmare. He realized that Claire didn’t just want him to fade—Claire wanted him to remember, to carry witness of the horror, to be part of its memory while it consumed all else.

Remember, Brian… remember…

He did. Every scream. Every handprint. Every twisted body. Every whisper.

Because he was Claire now.

And Claire was infinite.

The Lonely Planet Claire - Chapter 8: The Spread

From the place where Brian had fallen, Claire’s hunger began to ripple outward. The valley was no longer just a valley—it was a node, a heart pumping its influence across the planet.

The frozen bodies, that were once harmless remnants of the colonists, now writhed like snakes, stretching impossibly, their limbs splitting and fusing with the terrain. Blue veins spread across the hills, across the plains, into the air itself, carrying whispers that only certain ears could hear.

In the distant colony of Eslara, those still alive began to change first subtly. Shadows moved without light, doors creaked though no wind blew, and children complained of voices whispering secrets they shouldn’t know. Parents tried to comfort them, but the whispers knew their names too—and their fears.

Brian… come see… Brian… we are waiting…

The whispers became commands. Families vanished one by one, leaving behind only cracked, glowing handprints pressed into the walls, doors, and floors. Machines stopped working. Communications failed. Even the moons seemed to pulse with a strange rhythm, casting shadows that didn’t match the terrain.

Brian, trapped in Claire’s mind, watched it all unfold. He tried to scream, to resist—but his voice had become the chorus of the planet. He could only watch the terror grow, every disappearance adding to Claire’s strength.

From the center of the valley, the crater began to rise like a living tower. Black tendrils stretched from its peak into the sky, forming a network of veins that connected the moons, the wind, and the land. The planet was becoming aware on a scale beyond comprehension—every memory, every fear, every scream feeding it, including Brian’s.

A shadow formed above the valley, vast and impossible. It looked like a city made of darkness, flickering with blue light, yet it had no real shape. Those who glimpsed it through the haze felt their minds twist—seeing impossible angles, hearing voices of the dead speaking the language of the living, and knowing that the planet itself was watching.

Brian… Brian… you belong to us…

And in that moment, he understood: Claire didn’t just claim bodies or minds. It claimed reality. Anyone who fell under its gaze became part of its growing tapestry, a living memory woven into a nightmare that spanned the entire world.

The planet hummed. The moons pulsed. The winds carried screams.

And Brian’s voice, layered with hundreds of others, whispered along with it.

Soon… soon… soon…

Q & A: CGI

Q: With CGI what is the difference between green and blue screens?

A: Both green and blue screens serve the same core purpose in CGI and visual effects: they provide a solid, easily removable background so filmmakers can replace it with digital imagery. The choice between them depends on lighting, costume, camera technology, and the overall look of the shot. Here’s how they differ:

1. Colour spill and lighting

Green reflects more light than blue, which makes it brighter and easier to key out. However, that extra brightness also means it can cast a green tint onto actors or objects, especially around edges or in hair. Blue reflects less, so it produces much less colour spill. This makes blue screens better for darker, moodier scenes or shots with fine detail where spill would be a problem.

2. Camera sensitivity

Most modern digital cameras are more sensitive to green because their sensors typically use twice as many green pixels as red or blue (a characteristic of the Bayer filter). As a result, green screens often produce a cleaner, sharper key, especially in lower light.

3. Wardrobe and props

Anything close to the screen colour will disappear when keyed. If an actor is wearing green—army fatigues, foliage, superhero suits, creature costumes—filmmakers will use blue instead. Conversely, if there’s a lot of blue in costumes or props (ocean scenes, police uniforms, denim), green is safer.

4. Noise and detail

Blue screens often preserve more detail in certain materials, especially translucent or fine-textured objects like hair, smoke, or glass. This is why blue screens were used heavily in older film productions before digital sensors improved.

5. Lighting requirements

Green needs less lighting to appear bright and even, so it’s common for large sets and outdoor shoots. Blue needs more controlled lighting and is more often used indoors where conditions can be tightly managed.

In short:

Green is brighter, easier to light, and works well with digital sensors; blue provides cleaner edges, less spill, and is better for darker scenes or green-heavy wardrobes. Filmmakers simply choose whichever colour creates fewer problems for that specific shot.
