This article is for the story Tabula Rasa: Body, mind, and continuity.
- Paleolithic era: Humans evolve on Earth.
- 21st century Earth: Humans develop time travel, which starts off a long chain of events that affect many, many other timelines.
- 3.6 billion years ago: Visiplasts are introduced to Earth by a group of human time travelers, affecting the evolution of life, before they leave to explore the universe. The cancer cells from one of the time travelers later evolve into the nebulasa.
- Paleolithic era: Humans evolve on Earth, Tabula Rasa, and Gaia.
- 2020 AD Tabula Rasa: After a long and bitter war with the nebulasa on Tabula Rasa, the solar system and what remains of the nebulasa is eaten by a gigantic eldritch deity of the nebulasa. It eats Planet X, an artificial planet built by the Transcendence Commonwealth to store energy, in the process which boosts its mana energy by far, and it proceeds to reproduce and spread across to other timelines, destroying many Earths.
- 21st century: A time traveler sends multiple messages to the past in hopes of causing the Transcendence Commonwealth to prematurely collapse, allowing its massive stores of energy to be captured and used against the nebulasa.
- 16th century Earth: Mary Narase is born in Europe to a vampire, whose death from blood loss after childbirth was exacerbated by vampirism. She grows up to be a vampire herself, killing more than a thousand people and living for more than a hundred years.
- 17th century Earth: Lucia Cerise is born in France to Mary Narase, who abandons her for whereabouts unknown. She is taken in by a boarding school that trains children with unusually high amounts of mana energy to be self-sufficient witches and warlocks, where her name changed twice.
- 17th century Earth: Lucia Cerise is assassinated in France on suspicion of being a vampire.
- 20th century Earth: Dr. Rose Nacreous graduates with a doctorate from a California university.
- 20th century Tabula Rasa: Lucia Cerise is resurrected by Dr. Rose Nacreous in the Nacreous Laboratory, through the use of a time viewer and an extremely precise 3D printer for the brain.
- 199x AD Tabula Rasa: The planet is swept in a civil war, and the Transcendence Commonwealth collapses. Very few people know where Planet X is located at this point.
- 201x AD Tabula Rasa: The planet is attacked by the nebulasa during the civil war, but many more people are prepared at this point, having been given advance knowledge.
- 2020 AD Tabula Rasa: The deity of the nebulasa is destroyed after a significant portion of the energy from Planet X is weaponized. However, the region of space surrounding Tabula Rasa becomes extremely saturated with mana energy, causing environmental conditions and living beings to be unstable.
Magic in the Tabula Rasa multiverse was originally realized by scientists and descendents of time travelers on an early Earth, who figured out how to indirectly affect the outcome of events by controlling the flow of timelines that an individual's consciousness went across. The process was only achieved after a couple centuries of development in dimensional manipulation, which included time travel and travel to distant timelines, which are essentially other universes, as it required "hacking" an ancient branch of timelines with computer instructions to enable the physical impossibilities inherent in magic.
The second major component of magic consists of a group of parasitic microorganisms genetically engineered by humans, called visiplasts (from Latin vīs and Greek plastós), which invade living cells and then attempt to live in symbiosis with the organism. They store energy that would have otherwise been lost to the organism, often improving the efficiency of some biological processes. They produce manalin, a protein that converts other types of energy into mana energy and stores it. Large amounts of manalin crystallizes into a solid, and is often called manaite in this form.
Wands are thin, straight, hand-held rods often made of wood taken from magical trees, trees that produce a high number of visiplast organelles. Wands can also contain other materials with a high affinity for mana energy, although pure manaite tends to be risky as there is a high chance of death from either unintentionally expending all of one's energy in one spell, or being overwhelmed by a crystal extremely high in energy.
By serving as a magical extension of the user, they help the user conduct mana energy, as well as providing a location for the user to direct their spells. The tips of wands are often degraded from thermal exposure, especially when casting fire spells. They also tend to go through extensive wear and tear, as users will use them for many purposes, including stirring beverages.
- Staves are long, elaborate rods often made from magical wood, often with optional enchantments and decorations such as manaite gems, that assist mages in conducting magic. They tend to only be used by experienced mages, and are mainly granted to high-ranking scholars and military units for this reason.
- Flying broomsticks are vehicles fashioned from wood and straw high in manalin. Their main purpose is to orient themselves and the rider against gravity, and accelerate the rider through the air. They are typically enchanted with a cushioning spell that removes the discomfort of sitting on a pole for long periods of time, as well as preventing anything hanging from it from slipping off.
- Flying carpets are similar, being weaved from fibers high in manalin.
The majority of the time, manalin only provides a passive effect, causing the organism to be healthier and live a longer life, but this is typically offset by the fact that nearly all organisms have visiplasts anyway. As such, they often coexist alongside life without affecting its evolution, except on planets with high magical influence.
However, magic from visiplasts is utilized by some species, almost all multicellular. Very old trees and some species of trees tend to use mana to gain bulk and height, some plants and fungi use magic for defense, while dragons rely on it for flight and fire breath. Some animals learn how to use magic on their own, but only if their nerve cells have a sufficiently high number of visiplasts.
A magic user is able to cast spells by manipulating energy flow amongst every one of their cells, while particularly adept users can gather energy from the surrounding environment, including living things. It is possible to increase the number of visiplasts through training that encourages them to divide.
The majority of technological knowledge is concentrated on Tabula Rasa, but many technologies remain relevant long, long after they have been developed.
- Dimensional manipulation is traversal across spaces, times, and the voids between universes in a way that breaks the normal restrictions imposed by these dimensions. Faster-than-light travel and time travel are two forms of dimensional manipulation.
- Information technology involves computers and the networks between them. As high-speed calculators that can store, process, and transmit large amounts of information, computers have gained much use on Earth, and have been used for a long time on Tabula Rasa, although the Internet proper did not exist until the late 20th century on both planets. People commonly carry around a computer on them much of the time.
- Robotics are strictly regulated by the Transcendence Commonwealth. Sapient robots are not allowed except in highly restricted supercomputing situations, while semisapient robots are only employed in places with no human contact, like mining planets and asteroids. Nonsapient robots are highly specialized, and often employed in things that require automation, like food dispensing and building construction.
- Biotechnology includes genetic engineering, cellular restructuring, artificial cloning, and advanced medicine and pharmacology. Some people graft new body parts onto themselves for different reasons, functional wings being the popular example. Some people still use drugs recreationally, especially after the universal chemical dispenser, a "3D printer" for molecules, was developed.
- 3D printing is extremely precise and is used to manufacture many objects, including vehicles and body parts, especially human brains for resurrection.
- Terraforming is rare and prone to failure, as it requires seeding a primordial planet with a cocktail of organisms that can survive the environmental conditions and terraform it to favorable conditions over millions of years. Therefore, terraformed planets are opportunistically made through time travel and tend to be extremely expensive.
The majority of planets listed here are actually Earths from other timelines.
- Earth: Some magical influence, as there were secretive groups teaching it, who were persecuted by authorities until the end of the 18th century AD. Magical knowledge started becoming more commonplace with the emergence of the Internet in the late 20th century. Because of the presence of magic, history diverges, and they never develop dimensional manipulation independently.
Tabula Rasa: Extreme magical influence, the planet was colonized by the Transcendence Commonwealth, a group of time travelers who entered the timeline from another Earth and who wished to build a utopia. The planet was eventually swept by civil war in the late 20th century AD, and the Transcendence Commonwealth government collapsed. There is much less urban sprawl compared to Earth and the planet is environmentally pristine, although the surrounding galaxies are ravaged by mining and industrial robots from Tabula Rasa, who travel faster than light via magical teleportation.
Astronomical amounts of energy were stolen from the Transcendence Commonwealth and later used in major wars against the nebulasa, a class of ancient and eldritch aliens that had grown sometimes larger than a planet through mana energy.
- Gaia: Concentrated magical influence, the planet has a harsh wilderness due to the high prevalence of species that use mana and is relatively unpopulated. The planet was colonized by a group of time travelers that disagreed with the Transcendence Commonwealth on many issues. Most of the time travelers had extremely powerful magical abilities, and it was decided that Gaia be a universe where magic was used freely, even saturating some regions of the planet with mana energy so that mana-using species were more likely to evolve. As such, Gaia followed a history rather different from Earth and Tabula Rasa, where powerful humanoids worshipped as gods walked the earth and "supernatural" creatures like dragons existed. There are multiple terraformed planets in this universe.

The Nacreous Laboratory was a 10-story building built atop an island near the edge of a lake surrounded by the tall hills of a valley. The basement floors were occupied by a nuclear reactor, a water treatment plant, an AI and supercomputing core, a robotic factory, a medical bay, and a parking garage. The ground floor had a foyer that served as a hotel lobby, a large kitchen, and multiple conference rooms. The next five floors were filled with hotel rooms, while the two floors after these had larger apartment rooms with balconies. The upper two floors consisted of multiple laboratory rooms and some offices, while a greenhouse above them extended across the rooftop.
It was originally built as the remote and isolated residence of Dr. Albert Nacreous and later his daughter Dr. Rose Nacreous, after gaining access to a sufficient number of construction robots and raw materials from his time working as an important scientist under the Transcendence Commonwealth. A town formed nearby that had its electricity and water supplied by the laboratory. Both the Nacreous Laboratory and the town were generally unnoticed by the Transcendence Commonwealth, especially because it encouraged tall buildings over urban sprawl anywhere on Tabula Rasa.
