Historical Record
In 10191 the Emperor reassigns the fief of Arrakis. Heralds proclaim the transfer; carryalls and harvesters are inventoried; CHOAM auditors post notices as a noble house prepares to govern the desert source of the spice that underwrites interstellar commerce. The move triggers inspections of shield discipline, desert survival protocols, and the delicate accords that keep the great sandworms and human industry from catastrophic misunderstanding.
The significance is immediate. Every faction recalculates exposure: the Guild weighs transport guarantees; rival houses probe for weakness; Fremen populations watch from the deep desert, measuring newcomers by whether they waste water or learn. Policy memoranda stress ecology as strategy—control follows knowledge of wind, worm, and work. The year stands in the archive as the moment when ceremonial pageantry meets a frontier that refuses to bend to ceremony.
