Callax

Callax is a Ghost Stars daemon world also called the Gardens of Hell, a Slaaneshi pleasure-crust distinct from Chemos the Emperor's Children homeworld. This existing row is that Eye garden, not Chemos's old capital reused as a loyalist pin.

Fulgrim's sons treat Callax as a destination. The alias on this map is the whole warning: gardens, not factories. Callax is not Urum, not the Palace of Slaanesh itself, and not Chemos under chemos-system. Sibling planet Chemos already holds the Legion homeworld.

Callax still matters as the named Gardens of Hell. Unofficial fan summaries keep the Ghost Stars parent, keep the existing alias, and refuse to overwrite Chemos or to merge this pin with the Warp palace pin.
