I'm pretty sure this can NOT happen to the player, and that that event is designed as one of the Game-Destabilizing events. I.e. like the "Mega-Events" introduced in Dark Avatar, to help prevent the game from becoming dull.
But I would love to see such things be moddable, the possibilities are quite large, I can only imagine some of the great Random Event Mods players would come up with!
Perhaps if we jumped into the Elementals forums and started asking for Random Events to be moddable there, they may be come time for GalCiv 3.
