To run a Nobilis game, the players along with their Hollyhock God develop plots and campains based on the Nobilis extencive lore (or if prefered, using an alternative setting). The main premise can vary; the playable characters can be newmade Nobles trying to cope with their ennoblement, veterans trying to solve their own problems within their chancels, or soldiers of the Valdem Bellum fighting the Excrucian onslaught.
It all starts with a Campaign, which is divided by Scenes (and those Scenes can be sometimes tied together in Story Arcs). Players create their characters and begin to go on with their story as the HG guides their fates and decissions.
