The Glinthawk Heart is a medium-sized, organic-mechanical component harvested from the robotic Glinthawks in Horizon Zero Dawn. It features a central core with a pulsating, blue bioluminescent glow, surrounded by intricate metallic plating that mimics avian anatomy. The surface is a combination of smooth, polished metal and weathered, textured organic layers, with visible circuitry and fluid conduits that hint at its advanced technology. The heart's design is asymmetrical, with one side more heavily armored than the other, reflecting the creature's combat nature.
