Deadly Decadent Court: Half true. The Court of Courts and its lesser cousins certainly qualify as decadent, inasmuch as (a) those actually involved in the business of government at that level are very generously remunerated in order to (i) remove some of the incentive problems, and (ii) keep up the sort of appearances that make them look like the sort of people you ought to follow, and (b) the Privy Council and other courtiers, even many if by no means all of the entrenotres, tend to be drawn from the Names, Numbers, and Novas, which is to say, the core lineages, plutocrats, and innovative geniuses. Which is further to say, the most outrageously wealthy segment of an already outrageously wealthy society – and one which never evolved most of our quaint hedonism-is-bad memes.
Not very deadly, though. That went out when the runér replaced the korásan, whose costly political intriguing and tendency to consider sabotaging and assassinating each other in the course of zero- or negative-sum games thoroughly discredited this sort of thing, so while ambition continues and The Game has been reinvented, most of the competition these days revolves around outdoing each other at deeds which, if not always useful, are at the least not harmful, and flaunting the size of one’s (artistic/scientific/commercial/other) clientele.
