Add a new rule titled “The Continuum”:

Each Traveler is permitted to specify an algebraic Formula (to be tracked in the GNDT) relating five global time travel variables: ‘x’,‘y’,‘z’,‘w’, and ‘t’. A Formula is an equation relating least two distinct variables from this list. Each Formula must be well formed and in simplest terms, contain no transcendental functions, and not evaluate to indeterminate forms explicitly. A legal Formula must assign exactly one variable to the right hand side.

Some examples of legal Formulas are ‘x+y=t’, ‘300w/z = y’, and ‘x^2-t/(x+y) +1 = w’.

The Arbiter may erase any Formula that does not satisfy the above conditions, or edit any Formula for game / plot purposes.

A Traveler may, no more than once every seventy-two hours, edit one Formula in the GNDT, as long as the resulting Formula is legal.

Often, a Traveler may change the values of ‘x’, ‘y’, ‘z’, ‘w’, or ‘t’ as permitted by any of the legal Formulas that exist in the GNDT (provided that division by zero does not occur), then giving notice on the front page that this has happened.

If ‘t’ is greater than 6000, it becomes 6000. If ‘x’ is greater than 12, it becomes 12. If ‘y’ is greater than 31, it becomes 31.

If ‘t’ is less than -15000, it becomes -15000. If ‘x’ is less than 0, it becomes 0. If ‘y’ is less than 0, it becomes 0.

Often, a Traveler may set eir TL to [t]/[x]/[y], where [t], [x]. and [y] are the real parts of ‘t’, ‘x’, and ‘y’ rounded to the nearest integer.

Set ‘t’=1419, ‘x’=11, ‘y’=26, and ‘w’=‘z’=0. Create a GNDT column titled ‘Formula’. Create a new GNDT page and store the time travel variables ‘t’, ‘x’, ‘y’, ‘w’, and ‘z’ in it, and place a link to the new page somewhere on the sidebar.
