What you see above is Ivan the Terrible, Czar of All the Russias, who just realized that he has killed his own son during a rage.
It would be interesting for the PCs to get involved in a similar dramatic turning-point in a local ruling House – or even the Imperial House. What led up to this turn of events? What was the trigger to the fateful moment? What did the Noble do, when he realized exactly what he did? And what was the aftermath?
That’s one of the things I like about the Third Imperium: it isn’t some kind of impersonal bureaucratic machine, in the style of the First Imperium… or of the ‘managed democracies’ of today.
Men rule, men with names, names which are publicly known (as opposed to some responsibility-shunning, secretive power elite), men who are as often swayed by their emotions, tradition, family relations, and the demands of the people as by official policy, budgetary requirements, corporate expectations and formal regulations.
Sometimes, this is a good thing. Sometimes… not so much.
(But it certainly leads to a very exciting setting!)
