Order of the Cyan Storm
An order of the Adepta Sororitas based on Diaphone until the events of The Jormunga Cult where it was almost completely wiped out. The Order's primary base was a Basilica on one of the few pieces of land. It has a stained glass dome roof. The lower floors extend below sea level.
Some local variations of the Imperial Cult practised by the Order include burial at sea for the faithful but not the heretic, and some religious applications of salt water.
Sister Airi is one of four survivors of the Order.
