Heavy-world lineage with +1 CON, -1 CHA, poison resistance, and infravision.
The Dynar are a heavy-world human lineage, bred over generations for survival on high-gravity colony worlds. Their bones are denser than baseline, their stature compressed, their endurance immense -- every gram of their physiology adapted to crush-depth gravity that would hospitalise an unmodified human within a week. What began as a harsh-necessity survival programme during the early ark-diaspora became a stable germline: low to the ground, hard to move, harder to break. Dynar dominate in roles that demand raw physical toughness and an unshakeable anchor in a crisis.
