The Shield Wall has been breached in an atomic explosion. This is significant. This uplifted region of solid stone protects northern Arrakis from coriolis storms and sandworms. The Shield Wall makes civilization possible. To facilitate Spice Mining, many spicing stations are built atop the Shield Wall along the edge of the Deep Desert.

Now the sandworms have access to places previously denied to them. This changes the shape of things. Many smaller settlements have been adversely affected, and in some cases wiped out entirely. The question remains — is this the work of this Zantara figure? I suspect other hands at play. It’s a bold move to risk direct Imperial anger by endangering the spice trade. I must formulate a list of suspects.

Nature is a sculptor of stone and myth. She works in the medium of minerals and dreams. Consider the Stone Sentinel, the towering formation which resembles a great beast, perched atop the Shield Wall, holding eternal vigil over the Deep Desert.

Early Zensunni settlers oriented themselves with the landmark before the development of the paracompass. Young Fremem, undertaking the Trials of Aql, dared each other to make the treacherous ascent and stare the Sentinel in the eye.

Even geological features change. Wind and sand forever work the stone. It is only in relatively recent eras that the Sentinel wears its current form. Fremen poetically referred to the distant past as “Long ago, before the Stone Sentinel took off his Jubba cloak.” They also referred to the distant future as “When the Sentinel completes his watch,” denoting a time when he erodes entirely.

Your task is to incorporate these changes into the religious seeds planted by our Missionaria Protectiva in a time when the Sentinel looked very different. We must always bend and pivot. We must anticipate and adapt to changes in both in the micro-eternities between milliseconds and in the deep rhythms of geological time.
