Gler'rog are a furred, digitigrade species built around powerful pneumatic physiology, long balancing tails, and layered body-language communication. Males tend toward heavier frames, exceptional bracing strength, and upper-body force, while females are smaller, faster, and more agile, with rapid lower-chamber cycling and sharper directional control. Though physically formidable, gler'rog are especially sensitive to heat, pressure changes, poor traction, and full water immersion.
