Can someone please explain to me (or direct me to a thread to) Illyrio's intentions in Game of Thrones?
He essentially sells off Dany in order to acquire a Dothraki army for Viserys so on the surface it looks like he backs the heir. However later in the series we learn of his "fostering" of Aegon who he's been educating the past, what, 15 years(?) in efforts to create the perfect ruler.
I guess what I'm asking is if the Dothraki marriage was a pre-calculated fool's errand with the purpose of disposing of more legitimate candidates for the Iron Throne. Did Illyrio know Viserys would piss off the Dothraki and was he expecting Dany to become a non-factor in her marriage to Drogo? If so, why give her something extremely valuable like dragon eggs as a wedding gift. Not only could these have funded Aegon's campaign but also could strengthen his identity as a Targ due to the affinity they have with dragons (as well as the threat that he may be able to hatch them).
Lastly, if the plan was to dispose of D&V why send an agent like Jorah to merely report on their whereabouts instead of ensuring their demise?
What am I missing?
