Create a Dynastic Rule called “Setting” with text:

There exists a fictional timeline, which is not the same as the real-world timeline. All references to “game time” (including related phrases such as “game year” or “game date”) refer to the fictional timeline, and references to “real time” refer to the real-world timeline. No part of the Gamestate may be misinterpreted as referring to the wrong timeline, if it is clear to Arbiter in context which it refers to. The Core Rules and the Glossary only refer to the real-world timeline.

Create a Dynastic Rule called “Calendar” with text:

A Game Year consists of 365 Game Days, which are named in the same fashion as the days in a real non-leap year are named under the Gregorian calendar (January 1 - December 31). There exists a Game Year named for every integer (negative, zero, or positive), with greater integers naming years that come after ones named by lesser integers.

The “Standard Form” for any Game Date is “X/Y/Z”, where X is the year, Y is the month (an integer from 1 to 12), and Z is the day of the month.

Create a Dynastic Rule called “Whenever you go, then you are” with text:

Each Traveller has a Temporal Location (TL), which is tracked in the GNDT as a Game Date in Standard Form. New Travellers start at TL 1419/11/26.

Set each Traveller’s TL to 1419/11/26.
