What Does the First Night Law Actually Do?

[unmerged(220265)]

So I've loaded up as Aegon and am having a heck of a lot of fun building an evil slaver empire in the east. I have the First Night law set to legal, but I don't see any decisions for it, and I haven't gotten any events. Does the law actually do anything, or is it just for flavor?

There are a few random events. I got one where a generic peasant woman claimed I fathered her baby during the "first night" and had the option of acknowledging the kid as my bastard, giving her money, or calling her a liar (I suspect it's more or less a clone of one of the other random bastard events). Checking the event files, it seems that a lord with certain traits (e.g. lunatic) can claim the first night from one of his vassals when he attends a wedding.

Not sure why he would have to have the lunatic trait since it's supposed to be a noble right.

That's right...

The traits are required to try and enforce first night on your nobles when they marry. No traits are needed to use first night on peasants.
