Thanks to my spymaster I recently found out that there is a conspiracy of nefarious plotters among my vassals who plan the murder of my beloved son. As a ruler and father I am outraged by their insolence... that they didn't ask for my help!
I think murdering him is a great idea! I was looking for ways to decimate my offsprings for years (damn gravelkind succession, damn lustful + midas touched wife), and these guys are doing it for me without me risking to get my hands dirty. So I would like to do everything in my power to have them succeed.
Is there anything I can do to help them? Can I somehow get them to invite me to their plot, encourage others to support the plot or boost the plot power of those already involved?
