This is more a point of curiosity than anything useful, but these are the Storyline Points as they occur in the event data. You can alter where you are at in the story with 7F0000xx where xx is one of the following values.
Note that this will not allow you to do anything at any time, as a number of items are also controlled by flags in memory (for example, once Mount Woe falls, its gone for good).
