Tranquility System

The Tranquility System is an Endymion Cluster well in the Maelstrom Zone, the Mantis Warriors' recruiting gravity cluster rather than a peaceful shrine. Tranquility II is a feudal desert; Tranquility III is the death-world of the Valley of the Nine Winds; Tranquility I shares the chart.

Carcharodons hit this system in the Badab War's Tranquility Campaign, stripped a generation of youth, and left the Mantis Warriors without a training ground. This overlay does not invent a convent world or a T'au sept.

The Tranquility System still matters as the cluster the Carcharodons harvested. Unofficial summaries keep the Ultima parent and refuse to file the pin under a Sisters shrine of the same mood.
