In any case, his ability to wear the Amulet has nothing to do with his bloodline. It’s due to the fact that through the story of Oblivion, he and Martin are reenacting the ancient conflict between The Rebel and The King, echoing the relationship of Lorkhan and Akatosh and also of Zurin Arctus and Tiber Septim. My interpretation takes this down to the idea that, from a mythological standpoint, they are both equally fit to wear the Amulet and wield its power... in other words, to rule.
Could you elaborate on this? I don't believe I've had this idea put forward. I can sort of see this that Cameron is the Rebel Prince seeking to overthrow the Septim dynasty represented by Martin, but first of all I have never known an iteration of the Enantiomorph aligned with destroying the relationship of Lorkhan and Akatosh, and second of all, Martin, the king, prevails over the Rebel Prince, which does not happen in the Enantiomorph.
Unless both are potential Princes and they are struggling for control...
The possibilities based on this chunk of text are virtually limitless, so please elaborate so that I don't just go off on a wild (and wrong) tangent.
And with regards to the ogres bit, here's something to just throw a monkey wrench in your argument: Malacath claims that the Ogres are his. Or rather, are like the Orcs in that he is their patron.
