I also find it odd that a dead person speaks to the one who just murdered her....
It's not that odd, in fact in Shakespeare, classical epics, and the like, dead or dying people can speak at great length. Heck, the only reason Hector didn't in the Iliad is because Achilles had the intelligence to cut him off, tell him to shut up, and stab him in the throat.
Of course, if you really want they can replace the sovereign's picture with a picture of a piece of paper and an attorney who reads a will that says the same thing, but then takes half of it. Plus they could spend their half on demons of evil (they are lawyers) to make monsters more challenging and creating incentive to be cooperative instead of aggressive and violent.
