No scripts as far as I know.
Here is a great random event quest I just found:
<Description>The air crackles with the scent of lightning, and arcane magic. An energy has now been set loose in the world, an energy that feeds the savage in man and Fallen alike, an energy that strips away the mask of civilization, and lets loose the beast within.
All players declare war on every other player they know, unless they are in an alliance</Description>
Basically makes total war at a .0016 chance. A great preview of the event system.
