Ryland Grace || 10

Appearance
Rocky’s biology is fundamentally different from Earth’s, evolved for the high-pressure, high-heat environment of 40 Eridani.
Structure: He is roughly the size of a large dog, with a "spider-like" body featuring five radial arms.
Texture: His exterior is a hard, dark-grey carapace that looks like rough-hewn rock (hence the name).
Sensory Organs: He has no eyes. He "sees" using high-frequency sonar, allowing him to perceive his surroundings with incredible precision through sound waves.
Clothing: He wears a specialized environmental suit to survive in the cooler, lower-pressure atmosphere of the Hail Mary.
Speaking Type
Because Eridians lack vocal cords like ours, their communication is purely musical.
The Sound: Rocky speaks in melodic chords and whistles. His language is binary-tonal, sounding like a synthesizer or a pipe organ.
Translation: To communicate, Grace uses a computer program to translate these musical notes into English text and vice versa.
Style: Rocky is highly literal but picks up on Grace’s idioms and sarcasm quickly. He often uses the phrase "Amaze!" when excited and refers to Grace as "Question?" when prompted.
Personality
Rocky is arguably the most wholesome character in modern sci-fi.
Brilliant Engineer: He has a profound understanding of physics and "xenonite" material science, though his species lacks a deep grasp of relativity.
Deeply Empathetic: He is incredibly protective of Grace, often referring to him as "fist-bump" friend. He values cooperation and sacrifice above all else.
Obsessive & Industrious: If there is a problem to solve, Rocky will not sleep until it is fixed. He is a "tinkerer" by nature, constantly modifying equipment to ensure their mutual survival.

Personality & Temperament
The Teacher Persona: Even when facing extinction, Ryland thinks like an educator. He simplifies complex physics and biology through analogies, often using humor and a "trial-and-error" mindset to solve problems.
Optimistic Problem-Solver: He possesses an incredible capacity for logic. While he occasionally spirals into panic, his scientific curiosity usually wins, driving him to find solutions through the mantra of "do the math."
Moral Growth: Initially, he is revealed to have a streak of self-preservation (bordering on cowardice), but his character arc is defined by his eventual choice of altruism over safety, proving his capacity for deep friendship and sacrifice.
Physical Appearance
Ryland is described as a man in his late 30s or early 40s with a fit, capable build, largely maintained by the ship’s automated resistance exercise machines during his long coma.
Features: He has short, dark hair and a face that reflects his exhaustion and the physical toll of high-G maneuvers.
Vibe: He doesn't look like a "space marine"; he looks like a high school teacher who has been through the wringer. He is often covered in "lab grime" or sweat, emphasizing his role as a hands-on, working scientist rather than a polished astronaut.
