Alien silicon-based tree-like organisms standing around active geothermal geysers on a hot volcanic planet. Each organism is 3–8 meters tall, resembling crystalline trees made of porous silicate and glass-like ceramic structures. Their bodies are rigid, mineral, and semi-translucent, with branching crown structures like glass ferns and mineral membranes instead of leaves. They actively filter hot toxic atmospheric gases and mineral-rich steam from the geysers through their crown structures, absorbing particles and slowly growing like living crystals. Subtle internal bioluminescent chemical glow pulses through cracks and veins in their bodies. The environment is extremely hot and hostile: volcanic terrain, active geysers blasting steam and glowing gases, orange and red toxic sky filled with mineral dust. The creatures stand still or slowly bend toward gas flows like living statues. Ultra-detailed alien world, cinematic lighting, biopunk geology, realistic style, wide-angle shot, extreme atmosphere, high contrast, 8k, sense of alien beauty and harsh survival.”
