In the beginning of Magician Pug is adopted into the conDoin family for his rescue of princess Carline. By extension this makes him part of the royal family, somehting that Pug commented on a few times. Which would mean that he has a claim to the throne of the Kingdom of the Isles.
But what about Magnus? At the end of Shards of a Broken Crown Prince Patrick is such a jerk to Pug that the latter foregoes his claims and leaves the Kingdom's service. In my eyes this is more or less what Martin did at the end of Magician. Yet Martin's descendant Hal keeps saying that he has no claims to the throne because of what his ancestor did, but other people insisted that because no descendant did the same Martin did this doesn't count for Hal, and we all know how that ended in Magician's End. But wouldn't this mean that Magnus has a similar claim to the throne because he did not give up his claims either? Or do I see this the wrong way? I'm not asking if he would claim it (I figure that he would not) or how big his claim is, only if he has one.
