^That, and a more detailed history would be awesome :D It would be interesting to know how a former assassin would be tied up with the kingdom's affairs-- did he willingly offer his services to the crown? Did he realize that, perhaps, he had found a lord worth serving rather than just a shell of his former life as an assassin? Assassins are shady characters, especially in the kingdom, and as such, people find it hard to trust them. You would want to establish your relationship with the crown first (whether hostile, allied, or neutral) so that you'll have a smooth transition into the events.
For Jaiden, it's interesting to see another big brother figure other than Alistair. However, it would be good if a relationship was established between Jaiden and Lethonel. Did the servant enjoy researching as much as his liege? Did he like Lethonel at first? Did he even like to be recruited? Is being a servant all he dreams about? On a scale of Judas to Dog, how loyal is he? Does he have his own agendas? These things can help Jaiden feel more human :D Besides, Lethonel is a troublesome prince-- so, Jaiden better be prepared.
