History Main / BackgroundMagicField

* In Steven Brust's Dragaera, the presence of the Imperial Orb, and the ambient energies of sorcery, have turned the skies over the Empire orange.

* The Force from ''StarWars'' (although this trope is distinct from TheForce). While the Force is probably the TropeCodifier for a pervasive magical field in Western minds, its fundamental influence is more strongly felt in the ExpandedUniverse.
** To be more specific, there's a scene describing the Force as not only omnipresent, but abundant, and a little lizard exhales some in... was it The Courtship of Princess Leia or Truce at Bakura?
** In the Thrawn trilogy, an animal which nullifies the Force in a spherical area around its body is introduced.
** As explained by Penny Arcade, the Yuuzhong Vong (sp?), not normally being part of the Force, can be detected by Jedi only by them learning to be observant for where the Force isn't - apparently that's something of a counterexample, because it's apparently not like looking at a silhouette.

* In MageTheAscension reality is composed of quintessence, the "thread" of the "fabric" of the tapestry of the world. Everything is suffused with quintessence to varying degrees, and can have different Resonance, or magical impressions based on how the world perceives that object or person. For added fun, mages can make use of the Sphere of Prime in order to manipulate quintessence and restructure the magical nature of people and objects around them, including shutting off the flow of quintessence to such things, effectively erasing them from existence.

The BackgroundMagicField may be composed of, or easily turned into, {{Mana}}. Currents in the BackgroundMagicField may lead to {{Ley Line}}s. See also PlaceOfPower, MinovskyPhysics.

** ''{{Discworld}}'' does a fair amount of this. The Unseen University Library is the greatest collection of magic tomes on the Disc, so efforts must be made to avoid the magic going critical. ''The Science Of Discworld'' mentions that the last place to try splitting the thaum (the [[MinovskyParticle basic unit of magic]]) is now a very large crater, and anyone who explores it suffers weird consequences.

* In one filler arc of ElvesWithMecha, one character complains that the SteamPunk world he all-of-a-suddenly finds himself in has no MAgical feild Harmonics.

* BlazBlue has Seither, which is made of particles of the Black Beast. It is the power source for the Ars Magus, but causes harmful effects in high concentrations. Unfortunately, it has completely saturated the surface of the planet, meaning humanity is forced to live at high elevation.

* The ''Heralds of Valdemar'' series. Not only do ley lines run everywhere, but in places where they get muddled, Bad Things tend to happen. Like people and animals mutating, sometimes even overnight. Naturally, the Kingdom of Valdemar backs onto a whole wood full of muddled ley lines and mutated creatures, one of the remnants of the catastrophic war that occurred over three thousand years ago.

->While typically invisible to the naked eye, high densities of Mist will occasionally manifest in very visible phenomena. The highest concentrations of Mist can even do damage, leading to over-rapid changes in the environment, and violent behavior among animals and those more sensitive to the Mist's effects.

->The Force is what gives a Jedi his power. It's an energy field created by all living things. It surrounds us, penetrates us, and binds the galaxy together.

* ''TheWheelOfTime'' has the True Source, a sort of pervasive invisible magic that is available ''almost'' everywhere, except in Ogier steddings and the city of Far Madding, which block access to it through natural phenomena and ancient relics respectively. It can also be "stored" in some magical relics and used later in the aforementioned dead zones.
** In the [[CrystalSpiresAndTogas Age of Legends]], there existed something called the "Standing Flows" which enabled a variety of [[AppliedPhlebotinum magic-powered technology]], such as airplanes, to be usable by non-mages.

* ''TheWheelOfTime'' has the One Source, a sort of pervasive invisible magic that is available ''almost'' everywhere, except in Ogier steddings and the city of Far Madding, which block access to it through natural phenomena and ancient relics respectively. It can also be "stored" in some magical relics and used later in the aforementioned dead zones.

* ''TheWheelOfTime'' has the One Source, a sort of pervasive invisible magic that is available ''almost'' everywhere, except in Ogier steddings and the city of Far Madding (which uses some technology to eliminate it there). It can also be "stored" in some magical relics. When Rand [[spoiler:cleanses ''saidin'']] he does something very poorly explained with the magic energy, funneling it through some kind of filter.
** Its not exceptionally poorly explained, its just conceptually complex. The basic theory is that in the same manner that there are two halves to the one power that attract and repel each other there are two different types of taint in the world, the taint of the dark one and the taint of man called mashadar. The two taints hate each other in a figurative sense, attracting one another and annihilating like anti-matter. The metaphysics of the cleaning was creating a tube of saidar, connecting the tube to shardar logoth with its concentration of mashadar, then running a thin high pressure stream of saidin through the tubing. The tubing is permeable to taint and the taint on the source slips into shadar logoth attracted by the mashadar. Using the analogy of a the taint being a scum of oil floating on the surface of the infinite true source it is not itself infinite, merely vast. Also like mashadar the taint is self adhering. So the taint once is starts to slide off the source pulls the rest of itself off the source onto a corporeal location and then annihilates.
