Real life

Even though the Time Traveler's Net is fictional, real life does still influence many parts of it. There are certain things identical to the real life universe we live in, which are listed here for convenience.

Our own timeline is identical to Anchorage-15C, except of course, the future, where events are only predicted.

Multiverse
The multiverse our timeline is a part of is called the Prime Chronoverse.

Dimensions
Our own universe contains the 1st, 2nd, 3rd, and 4th Dimensions of Anchorage-15C, 5D and beyond are outside of what real life contains.
