Tranquility I

Tranquility I is a numbered world in the Tranquility System of the Endymion Cluster, the least-documented rock in the Mantis Warriors recruiting well rather than the death-world of the Valley of the Nine Winds. This map keeps it under tranquility-system beside researched Tranquility III.

II is the feudal desert that took Dark Eldar and Ork pirates; III is the jungle fief Carcharodons harvested in the Badab War's Tranquility Campaign. I shares the chart and the Maelstrom weather without a published campaign of its own. This overlay does not invent a convent or a T'au sept to fill the gap.

Tranquility I still matters as the first numbered sibling in that well. Unofficial summaries keep the Ultima system parent, refuse to steal III's training-ground dossier, and do not merge this row with the leftover un-numbered Tranquility pin.
