Craftworlds are massive, spaceship-like habitats used by the Aeldari race in the Warhammer 40,000 universe. These vessels are designed to preserve the remnants of the Aeldari civilization, which was nearly destroyed by the catastrophic event known as the Fall of the Aeldari. Each Craftworld is home to a distinct culture and way of life, with its own unique traditions and practices. The inhabitants of Craftworlds are known as Aeldari or Eldar, and they often focus on the pursuit of psychic abilities and advanced technology. Each Craftworld is equipped with powerful weapons and defenses, allowing them to navigate the galaxy while avoiding threats from other factions, such as the Chaos forces and the Orks.
