Section: Recording Landmarks
Landmarks will only be recorded the first time they are reached. You can locate the time a landmark was hit by using the "time (landmark) occurred" phrase. Furthermore, we can test the following:
if reaching the city walls has happened ...
if emerging from the forest has not happened ...
if emerging from the forest happened after reaching the city walls ... (or before)
if singing for joy and emerging from the forest happened together ... (ie. on the same turn)
Note that comparisons are made by the game clock, so two events happening on the same turn will fail a "before" or "after" test, but pass a "together" test.
