Prandium System

The Prandium System is Ultramar's ruined garden well, an agri-jewel Hive Fleet Behemoth stripped of even the air in 745.M41. Remus Ventanus had already wrecked tracts of it in a Heresy-era Codex trial against mock World Eaters, and the world later healed before the swarm arrived.

Calgar's defence failed. Two centuries on the Ultramarines still treat the loss as a stain. Prandium remains a child of the Ultramar Sub-sector rather than a random Ultima dead world.

The Prandium System still matters as the garden Behemoth ate in public. Unofficial fan notes keep the Ultramar parent and refuse to pretend the jewel grew back.
