Invisible Sun is a roleplaying game of surreal fantasy.
The player characters are vislae—wielders of magical power—recently returned to their true home: the Actuality, a world that seems like a surreal dream to those of us toiling aimlessly in the boring, grey realm you and I falsely believe is the real world. These characters face incredible challenges, visit breathtaking places, and discover secrets so astonishing that the only ones who can cope with them are those who understand the truth that powers the universe: Magic.
Magic: A power that can be pursued, studied, and even mastered, but never completely understood or controlled. It is fluid, unpredictable, and ever nuanced in effect. Its secrets are boundless. But that does not mean it is without rules and methods. There are four orders, major schools of magical thought and training. Vances study their spells carefully, believing they are, in their own way, intelligent in and of themselves. Makers, as the name suggests, use magic to create powerful items. Weavers cast spells with a fluid and improvisational sort of sorcery. Goetics use their magical skills to summon demons, angels, and other creatures to do their bidding. Outside of the four orders, Apostates are vislae who find their own paths and methods for wielding the power of magic, rejecting the hierarchies of the orders.
It is a rare vislae who does not have a house. Your house is as integral to your being as your spells or character stats. The houses of vislae are often haunted, filled with mysterious unknown rooms, bigger on the inside, or possessed of their own intelligence. And in Satyrine, a house is defined as much by what goes on around it as by the contents of its walls (assuming, of course, that a vislae’s house even has walls). Local personalities, sites of interest (or danger), organizations or factions, and ongoing conflicts all affect a vislae’s house and life. And all of this is determined as part of the character creation process.
There are many creatures cataloged within the Black Cube, but the Actuality is a big place. Every day, new entities and surreal beasts are discovered by explorers, conjurers, and other (often unfortunate) individuals. Numerous vislae have given their time, effort, lives, and so much more to compile this ever-growing collection of creatures, which most in the Actuality consider to be the greatest resource on the topic.
