re Macbeth, it's believed likely that parts of the play were lost on the way - no doubt the parts that support my case. There's a "fun" Shakespeare game involving mixing the heroes and plays - say Othello was Prince of Denmark. This doesn't sound promising in the Dragaeran universe (what if House Jhereg was ascendant in FHYA, for example - maybe Mario would be awarded the Orb?) but it's a good way to understand implications of character so maybe someone has some good mix/matches to propose.
