Time travel

Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically with the use of a hypothetical device known as a time machine. Chrononauts and its three expansions are based around the idea.

Before Time Travel
Before time travel, people from the future were still travelling back and forth, right under the people of the past's noses. However, this was rarely noticed. One account states that artefacts have been stolen by time travellers for millions of years, and that they replaced them with fakes so much it was hard to find who actually had the original.

In fact, in one timeline, the universe was destroyed in the 1940s by a clumsy time traveller.

One chronohistorian Renee went all the way from the year 2112 to see the Titanic, but the accounts were wrong and it sank 9 minutes early. Renee died on the titanic, creating a paradox which could only be fixed by changing the titanic's sinking, so Renee was propelled into a parallel reality.

Invention of Time Travel
It is unclear when Time Travel was invented, and who invented it, but it, in the standard timeline of Chrononauts, it could have been invented as early as 2009, as that is the year just outside the standard area of time which time travellers going to the past go to. In a different timeline, everyone had pocket time machines by the 1960s, but by the 2000s none were left apart from Minkoff's. Most likely, it was discovered in the 2020s and spread popularly across the world.
