What are the picture files...

... for the events like Heir born, princess assassinated, etc?

Hi,

it's one file only, campmap\Epic.bif. But you'll have to figure out for yourself which event-pic is placed on which position.
You can use this thread to get a grip on the topic:

Ok, thanks,
I had the NTW one in MTW (somehow) so I wanted to know which ones so I could import the one from FORTW so,
I just replaced about all the bifs though so that fixed it sort of.
