Nobilis: Seasonal Flux
Any Imperator is dangerous, potentially deadly, even to the PCs (who are theoretically on the same side). Full Excrucians, however, are the stuff of nightmare. PCs face them only rarely, because almost every Imperator on Earth spends day and night keeping full Excrucians from reaching the material world – but it happens. When it does, the first rule is “run away, if you can” – because Excrucians are not on the same side. They have Gifts and Foci that can affect Powers directly and don’t take the hours or days Imperial miracles require. They are sneaky and dirty and beautiful and full of hates and compellings, and the warriors that lead them wear the faces of the dead.
The Excrucians come in four breeds, or perhaps four castes; it is not whether these distinctions are a matter of birthright or training. An Excrucian is either a Warmain, a Mimic, a Deceiver, or a Strategist. Bear in mind these words are translations.
And that, dear friends, is all I’m going to tell you for now.
