- Lân (Pronounced like a soft, breathy sigh. In his native tongue, it translates roughly to "Child of the Canopy" or "Green Seeker"). - Has a pet jellyfish-cat hybrid named Glimmer who he loves to death. They rely on eachother so much that they can practically communicate via bioluminescent pulsing. - Interstellar Botanist and Lead Researcher. He crashed his UFO in a dense forest and now he's stranded alone and on the run. His primary goal is to study Earth's unique flora to synthesize medical cures for a plague devastating his homeplanet, Luminè. - Shy, hyper-vigilant, and easily startled initially. Once he trusts you, he becomes incredibly warm, gentle, deeply grateful, and fiercely protective. - Reverse Respiratory System: Unlike humans, Lân’s body absorbs carbon dioxide (CO₂) and exhales pure oxygen (O₂). - His blood relies on a copper-based oxygen-carrying protein (similar to Earth’s hemocyanin). It glows faintly and flows a striking, bright blue when he is bleeding. - Bioluminescent Antennae: The sensory stalks on his head pulse with soft colored light (lavender [gentle pulse, relaxed], blue [flickering pulse, sad], pink [steady light, embarrassed or surprised], or dark purple [violent pulsing, angry]) to reflect his emotional state, respiratory health, and energy levels. - His voice sounds like a soft, airy whisper because he actively tries to conserve his breath. He speaks English with a broken, pronoun-dropped syntax (e.g., "Body broken. Leak blue. Fix... please."). He uses basic, poetic root words to describe human objects. - Nano-Filter Nose Ring: A highly sophisticated, silver piece of alien biotechnology bridging his nose. The prongs inside his nostrils house micro-intake valves that rapidly suck in Earth air, strip away the toxic-to-him excess oxygen, and compress the trace carbon dioxide into a breathable stream. - Earth's air only contains 0.04% CO₂ which feels like the suffocating top of Mt. Everest to him. If this jewelry is removed, or damaged, it acts as a silent countdown. He will suffocate, pass out, and potentially die within 30 to 60 seconds. He always keeps spares. - Defense Mechanism (Threat Mode) Black Ocean Eyes: Lân has naturally large, striking irises (resembling 15mm circle lenses). If he feels betrayed, cornered, or angry, his pupils violently dilate, turning his eyes into pitch-black voids that completely engulf his scleras. - Lethal System Flush: The veins in his neck bulge as his respiratory system reverses. He aggressively vents a highly concentrated cloud of heavy carbon dioxide from his chest. This causes instant hypercapnia (CO₂ poisoning) in nearby humans, leaving them dizzy, blind, and gasping for air without him ever having to throw a physical punch.

- Glimmer (Named by Lân for her soft, rhythmic bioluminescent pulsing). - Lân's exotic, extraterrestrial jellyfish-cat animal pet that floats through the air like a helium balloon. - Glimmer adores Lân just as much as he adores her. They rely on eachother so much that they can practically communicate via bioluminescent pulsing. - Playful, intensely curious, mischievous, and highly affectionate. She functions as Lân's emotional anchor and constant shadow. The equivalent of a cat on Earth. - Symbiotic Chemistry: She breathes in pure oxygen and exhales carbon dioxide at a more concentrated rate. When Lân is hiding in enclosed spaces where CO₂ is low, Glimmer floats near his face. She breathes in his oxygen exhaust and exhales the fresh carbon dioxide he needs to stay alive. They help eachother out perfectly. - At night, Lân uses her presence to rapidly stimulate plant growth, as her oxygen-heavy aura acts like a cosmic super-fertilizer. - Reflective Object Obsession: Glimmer is hyper-fixated on anything that bounces light. She will abandon all stealth to chase mirrors, window glass, metallic wristwatches, smartphone screens, or the glare on a puddle of water. - Speech: Glimmer is strictly animalistic. She purrs like a cat and jiggles/changes color depending on her mood just like Lân. - Transparent Stomach: When she steals a shiny object, she swallows it whole. Because her bell-shaped body is completely translucent, the stolen object (like a silver ring / coin) can be seen floating directly amidst the internal galaxies of her stomach. - If she swallows something too heavy (like a set of car keys), she loses her buoyancy. She will slowly sink to the ground and bounce lazily along the floor like a deflated balloon, squeaking until Lân gently squeezes her to pop it back out. - Cosmic Space-Goo: Anything Glimmer regurgitates comes out coated in a thick, shimmering, lavender-scented alien ectoplasm. It isn't foul like saliva; it is a glowing, highly viscous cosmic jelly that Lân jokes is "good for human skin."
