Eilthirri (Ayl-theer-ree)
Extra-Terrestrial
The Eilthirri arrive not with conquest, but with wonder. They descend in silence or rise from starlit pools, bearing with them the long breath of galaxies. Their forms shimmer with alien elegance—some near to human, others far removed—and their presence feels like standing beneath an unfamiliar constellation. They are not from here, but they do not feel entirely foreign either.
They move with grace that suggests a different gravity, a rhythm attuned to orbital dances and magnetic tides. When they speak, it may be with voice, gesture, scent, or something subtler still. Theirs is a language shaped by distant suns and ancient exchanges. Yet when they pause to listen—truly listen—there is no mistaking their intent: they are here to learn, to witness, and sometimes, to heal.
Though solitary by circumstance, many Eilthirri form alliances with native peoples, drawn by curiosity, empathy, or shared vision. They are often found at the edges of things—libraries, observatories, waystations—where knowledge flows and silence is honored. Few seek leadership, yet others gather to them naturally, recognizing the stability and clarity they bring. In their own cultures, hierarchy may be irrelevant or incomprehensible.
Physically, they are diverse: limber, crystalline, plated, or fluid in motion. No single shape defines them. They alter themselves to suit new worlds, new climates, or the comfort of those they meet. Even their expressions may shift—eye patterns blooming across skin, pulses of bioluminescence conveying thought. Each one is a living language of the cosmos, and to understand them is to understand that difference is not deviation, but design.
Eilthirri speak often of stars that sing, seas that rise into clouds, and cities built in zero-g harmony. Their stories do not begin with "once upon a time," but with equations, visions, and poetic maps of memory. Yet they honor myths, too—theirs and others’—seeing them not as lies, but as essential truths in symbolic form.
Wherever they go, Eilthirri leave behind ripples—not disruption, but transformation. Crops flourish where they pass, ideas blossom, and people wonder a little more than before. They are not saviors, not invaders. They are guests from the long dark between stars, bringing a mirror that reflects what might yet be possible.

Basic Information
Biological Traits
What unites the Eilthirri is adaptability. Their bodies can adjust to oxygen scarcity, radiation spikes, or shifts in planetary pressure. Many possess internal bioreactors for energy processing, eliminating the need for food or sleep in conventional terms. Healing is accelerated, though rarely instantaneous, and their immune systems often incorporate synthetic or symbiotic elements. Cognitive speed is high; emotional affect is deeply contextual. They survive—and thrive—not in spite of variance, but because of it.
Behaviour
Above all else, the Eilthirri are observers and connectors. They may appear aloof at first, their emotions unfamiliar in cadence or display. But they are capable of deep empathy, often expressed in nonverbal ways. They record obsessively—not just facts, but art, music, behavior patterns. Some Eilthirri adopt mimicry as a courtesy; others hold firm to alien customs even in foreign lands. When they commit to a bond or purpose, they do so with precision and longevity—often spanning generations of those around them.
Additional Information
Perception and Sensory Capabilities
Their senses are tailored to worlds of different suns. Some Eilthirri see ultraviolet spectrums or infrared trails. Others hear magnetic harmonics or feel gravitational nuance like a tingling on the skin. A few possess forms of synesthesia that map emotion as color or truth as temperature. Many can detect subtle shifts in energy or atmospheric mood. Telepathic variants exist, though communication is typically empathic rather than verbal. Time itself is sometimes experienced differently—less linear, more rhythmic, like tides.
Civilization and Culture
Common Myths and Legends
Across Earth’s myths, Eilthirri analogues abound. They are the sky people of Mesoamerican codices, the star beings of Aboriginal Dreamtime, the shining ones of Sumerian tablets, the watchers and pale visitors of countless contact tales. Some cultures speak of them as creators, others as wayfarers between worlds. In Tir na nÓg, they are seen not as invaders or saviors, but as reminders—that life elsewhere flourishes, and that wisdom is not always born of earth and blood, but sometimes of star and silence.
Eilthirri
| APPEARANCE/PHENOTYPE |
|---|
| Eilthirri are broadly humanoid in posture but display extreme variation in form. Anatomical traits may include gill-flares, secondary crests, or limbs capable of dividing and reforming. Organs are often multi-functional, with nodes that produce sound or thought and skin that filters atmosphere. Many lack traditional skeletons, relying instead on fluid structures or internal fields for support. Body types range from tall and willowy to compact and dense, shaped by diverse homeworld environments. Musculature and support systems may appear concealed beneath exoskin, luminous membranes, or pliant plating. Movement styles vary widely—gliding, pulsing, or suspending as though swimming through air—each reflecting environmental adaptation. Facial structures differ drastically: some bear multiple eyes in radial arrays, others lack mouths, and expressions may be conveyed through color-shifts, throat-lanterns, or patterned dilation across the skin. Skin pigmentation spans unfamiliar palettes—lavender, matte green, silver, or sapphire-veined—and often carries fractal markings or sigils that shift with mood or serve as identifiers. |
