Adrantis Nebula Subsector

The Adrantis Nebula Sub-sector is the Calixis cube around a light-years-wide gas cloud, once home to the Adranti people Lord Militant Angevin later erased. Aeldari charts still call the cloud the Calexis Nebula.

Tranch's Pale Throng, Baraspine, Tephaine, Mortressa, and the Hippocrasian Agglomeration share the soot. Magos Genetus Halix Redole hunts genetic corruption here; the nebula is scenery and a grave as much as a border.

The Adrantis Nebula Sub-sector still matters as Calixis's dusty laboratory, not as a random Obscurus label. Unofficial maps keep the calixis-sector parent and leave Tranch a child rather than the whole article.
