Scintilla is the capital world of the Calixis Sector, and the Imperial Hub for the territory. There are two great hive cities, Hive Sibellus and Hive Tarsus, with their billions of residents, compete for honors and trade. The Sector Governor Marius Hax rules from the Lucid Palace on the Hive Sibellus, where the rich and powerful compete for the eye of Marius, and by extension, the Imperium. The other feature that all Acolytes will be aware of is the Tricorn, which is the palace of the Inquisition on the world. The High Council of the Calixian Conclave meet here, and it is from this palace that the Lord Inquisitor Aegult Caidin, rules and watches over the Inquisition in the sector.
There are many other places of interest and information necessary for the Acolytes on p. 290 – 300 of the Rulebook.
