- "Before Common Era", e.g. 27 BCE, the date Augustus becomes Rome's first Emperor.
- Black Fleet
- Second Black Fleet
- Third Black Fleet
- black hole
- the speed of light.
- "Common Era", e.g. 2010 CE, the date the wTc was activated.
- Central Intelligence Agency, the black-ops organization operated by the United States of America started in 1947 CE.
- a constructed language, e.g. Tarazedi or Klingon.
- Continuity Project
- the Deep
- the plane(s) below planispace, usually inaccessible, that include physical laws. Some sentients interpret the Deep as infinity or God.
- an interstellar, intergalactic, or intertemporal evacuation of a society from its home spaces.
- fusion torch
- an interplanetary or interstellar drive that utilizes a fusion reaction as a power source and accelerated plasma or electromagnetic radiation as a propellant.
- "giga-years ago", used for dates one billion years or more before present. e.g. 4.53 GYA, the date of the last major event in Earth's formation (the Theia collision) forms Luna.
- "giga-years hence", used for dates more than one billion years after 2000 CE, e.g. 7.5 GYH, the date Earth is consumed by Sol's expansion to red giant.
- "in real life", i.e. non-fictional.
- "kilo-years ago", usually used for dates more than ten thousand years before 2000 CE, e.g. 15 KYA (13000 BCE), the date of the Holocene extinction event.
- a planispace nexus that manifests as revealed documents or mysterious artifacts, usually causing dangerous spiritual disruption to human societies as pieces are discovered, recovered, or lost.
- "mega-years ago", used for dates more than one million years before 2000 CE, e.g. 65 MYA, the date of Cretaceous-Tertiary mass extinction.
- "mega-years hence", used for dates more than one million years after 2000 CE, e.g. 300 MYH, the date of the formation of Amasia supercontinent on Earth.
- observer drive
- a system that uses a conscious quantum observer to manipulate universal constants by specific factors within a defined region. Also known as a "Liar Drive". Most commonly, an observer drive uses a living consciousness to multiply the speed of light within its field and simulate faster-than-light travel. Other applications include fusion pumping, where a reactor's output is increased by altering the speed of light, and artificial gravity or anti-gravity where the gravitational constant is altered.
- one of the eight self-chosen castes in Quatran culture.
- First Paradigm War
- Second Paradigm War
- Third Paradigm War
- the plane(s) that underlie Reality, connecting different aspects thereof. Planispace may be viewed as the surface layers of an ocean, with a distinct interface with the sky and an indistinct interface with the deeper waters. Planispace exhibits the properties of the collective unconscious and may, from the perspective of Reality, appear to defy the laws of Reality. Under certain conditions, either technologies (e.g. observer drives, Shai-Gates) or spiritual means (e.g. dreams, meditation, sex, intense focus) may be used to access and utilize planispace utilized though usually only with great difficulty and often with major and unforeseeable consequences. Planispace has currents, which affect events. Psionics operate through this medium. May also be considered spirit.
- planispace nexus
- a planispace feature where disparate planes of Reality converge, often allowing sentients direct awareness of or access to planispace.
- planispace stream
- the interfacing of a sentient with planispace, manifesting as "paranormal" abilities such as telepathy, telekinesis, precognition, etc. All sentients have the potential for psionic ability, however, realization (especially conscious realization) of this potential is exceedingly rare.
- the Purge
- Rashi AI War
- the plane(s) that result in the visible, physical universe (and potential alternate and unmanifest universes).
- Renewal Process
- Rta Flower
- the Rupture
- Salamander Eggs
- the Shift
- the Second Shift
- the Third Shift
- Sino-Indian War
- Sino-Oceanic War
- Tav Plague
- Tzadi Nexus
- a planispace nexus considered to be the pinnacle of human evolution and the effective end of human history.
- unity consciousness
- the ability of sentients to subsume their consciousness into the Deep, usually with others.
- First War Before The Abyss
- Second War Before The Abyss
- a distinct history following all events within a universe. Currents in the Deep, planispace, and to a lesser extent Reality, may also result in new causal worldlines being formed. Infinite parallel worldlines exist, and may sometimes be bridges via planispace nexi or the actions of sentients.
