The Continuum is the center of the solar system. It is the well from which all magics flow, and is so powerful it even emits magic on the visible spectrum - acting in place of a natural star as far as light for daytime goes. Unlike every other fount of magical energy, the Continuum has no - recorded - Summoners, elementals, or inhabitants.

The closest planet to the Continuum, Fire planet is a hard, little rock mostly covered in desert. The only exceptions are the two volcanoes and the river by which both the Summoner's palace and the only permanent city are built. It is also home to a number of people important in the system; Bryn Cosaint, her mother Amelia Cosaint, and the inscrutable Fire elemental called Zeem.

The Water planet is the only one in the Continuum system without any landmasses and a permanent population of exactly 1 human. Other humans can and do visit, and create temporary structures for living when they do; the Company facility of LAST SHORE was one such, and it stretched for almost a mile vertically to be anchored to the ocean floor. The Summoner and single permanent resident of the planet is Summoner Zulimar; non-permanent residents include Company employees Herr Dobyns and Gwennaig ar Merer.

Lightning's geography is made up largely of rolling plains and shallow seas; for all that vicious storms rage frequently across the surface, they have more to do with Lightning magic than rain and the sea level tends to stay pretty static. There are a small number of Company facilities on the planet, and most of the population tends to live in reasonably sheltered - if isolated - villages. Lightning is the home planet of Rex Leonine, though she hasn't been back in decades.

The most populous by far of all the planets, every square inch of landmass - and, thanks to technological advancements, a decent amount of the lakes and oceans - is covered by the City. Home to more than six billion people, the City changes architecture with the geography, but it never truly stops; the only green and open areas are the ones specifically set aside as gardens for the affluent and powerful. Void planet is home to a lot of people, and Sam Haugen, Puq, Professor Baxter Brautigan, C-NACK88, Corvix Filibust, Ira Dietrich, Ms. Kale, Fidditch Kale, Sofia Morelli, and countless others were born and raised there.

While it would be untrue to say that Bloom has no large areas of open water, they are exceedingly difficult to see through the jungle canpoy that covers nearly the entire planet and makes surveying by satellite somewhere between difficult and impossible. The capital of the planet, Homestead, is home to less than 10,000 people - and that includes the Company employees who maintain residences there while working at the nearby Company installation, the Elder Seed Facility. Summoner Langorium was the most recent Summoner of the planet, though the position currently stands vacant; Tara also hails from Bloom, but has recently been transferred to Haven by request.

The furthest planet from the Continuum, Blight is a stinking, unremitting swamp; stagnant bogs lead to dying bayous which transition to festering swamps, and more. The only notable location left on the planet is the Summoner's abode, Blight Manor. Both Ezra Caepio and Figmot called the place home, but the population is small and getting smaller.

A rogue moon that orbits the Continuum directly, Cylvahl Cylesso is the closest celestial body to the Continuum itself at less than 1.5 light-minutes. It's small enough that the only significant settlement is centered around the Monastery of the Parallel Order, and houses fewer than 5,000 people. Tag, Variq, Maksha, and a few others call the moon their own, though technically only Tag was truly raised there.

An experimental dropship, the Void Jumper was specifically engineered with extra shielding to allow it to nullify and pierce barriers both magical and mundane. It has no steering thrusters, and instead relies upon the force of local gravity to guide it to its destination. To get it off-planet again requires a special towing shuttle and a highly trained tow pilot.

Betwixt and between the world as people know it and other planes of existence, the Phase State is a barrier as much as it is a realm all its own. Most of the time it resembles idealized versions of the physical world; some details may be exaggerated or distorted depending on the viewer's perception of them, but it is nevertheless a representation thereof. Many realms lie beyond the Phase State, but few of them ever attempt to cross the Phase boundary.

One of the many realms beyond the Phase State, the Malice takes an active and inimical interest in the mundane world. According to some denizens of the Malice, at one point the two were not separate at all; whether or not these reports are reputable remains in dispute. No matter what the past was like, the fact remains now that the Malice would like nothing more than to see the mundane world crumble in upon itself and be destroyed.
