Necrons Portal

Tomb Worlds are the worlds which have been inhabited by dormant Necrons for millions of years. Their worlds exist in unknown numbers throughout many parts of the galaxy. A Tomb World is seemingly long abandoned, and many are thought to be the ancient worlds of the Necrontyr, since their architecture shows up on many of the planets. Tomb worlds have a tendency to be barren and lifeless desert worlds.

Many Adeptus Mechanicus personnel sent to these planets for exploration are often never heard from again; the vile Necron inhabitants never having truly left over the millions of years they had been in stasis.

Types of Tomb Worlds

• Crownworlds: Were once the hubs of galactic Necrontyr power. Necrons from crownworlds tend to have survived the great sleep in excellent condition and the worlds are untouched by disaster or other races. As a result, these tend to be the hubs of Necron Dynasties and the Necron Overlords rule from them.¹¹
• Coreworlds: Are next in importance after crownworlds. These planets form the heart of a Necron Dynasty.¹¹
• Fringeworlds: Are planets of tertiary importance, not viewed as being high enough in status to be numbered amongst a dynasty's coreworlds. Fringeworlds tend to be poor and distant colonies, used for manual labor.¹¹
