The Eidolon Gantulyst is a towering, biomechanical entity with a sleek, armored exoskeleton that reflects a fusion of organic and synthetic materials. Its body is predominantly angular and symmetrical, featuring glowing blue energy veins that pulse across its surface, indicating its Sentient origins. The Gantulyst's limbs are elongated and end in sharp, blade-like appendages, while its central core is protected by layered plates that can open to reveal a vulnerable, luminous weak point during combat.
