Tried to delve deeper into the topic of lamentation:
For now, this is all that comes out. But I don't really like this kind of explanation.
Reread the description of the White Night's role - it doesn't say anything about the northern war, so it's worth digging further in this direction... Did anyone happen to kill any commanders from some northern wars in their beds?
But "lamentation" shouldn't be dismissed either; why would the GM come up with such complex names for fictional authors of news reports? Why would they come up with names at all!
