The fabric of reality is delicate. Each aspect of reality has its own ‘fabric’. These are known as the universal continuum and the astral continuum.
Each continuum has a number associated with it, and this number is variable over time and space.
The Universal Continuum
The Universal Continuum is weakened mainly by large masses. Look up the gravitational pull of large objects (in Earth gravities) on the Doubles Chart, for the Universal Continuum. The sun’s gravitational pull is 27.9 gravities. At the ‘surface’ of the sun, the Universal Continuum is 5.
The Astral Continuum
The Astral Continuum is weakened by large populations of sentient creatures in one area. Look up the billions of intelligent creatures in the area on the Doubles Chart. Earth has four billion people. This gives it an Astral Continuum of 3.
Breaking Down the Barriers
The continuum number is the chance, on 2d10, that the continuum will break down when the continuum number changes. If the Astral Continuum suddenly goes from 3 to 4 in the heroes’ headquarters because the wizard cast a spell that raises the Astral Continuum, the continuum will break down on 4 or less on 2d10. When the continuum returns to normal 1 day later, it will break down on 3 or less.
Temporary points (because of spell use or time travel, for example) disappear at 1 point every 1/2/4/8/etc. days.
Continuum breakdowns last a number of hours equal to the Quality of the breakdown roll, read from the Result column to the Sphere column. What happens when it breaks down? Travelers from the other side can get through to this side, and travelers from this side can get through to other parts of the Universe, other Universes, or other Astral planes.
Localized Disturbances: When mass or energy is transferred between universes, times, or time-lines, a localized disturbance in the space/time continuum will result.
Look up the amount of mass that’s been moved (in kilograms) on the Doubling Chart, for the amount the space/time continuum is increased by. If it’s energy, look up the number of d6 that the energy does, on the Doubling Chart. As the energy disperses, the continuum will return to normal, as given for temporary points.
Results of Weaknesses: The higher the continuum number, the easier it is for characters or items that travel times or time-lines to break through the time/space barrier—increase the chance of successfully materializing in the new time/time-line by the continuum number times 5.
