Oh yes! One of the best endings ever! Only to be completely wasted and never followed up on.
I have mixed feeling about the series, mostly, I'm sure, because I'm an old school fan, who grew up on the Noble Sub-Mariner, not exactly the Namor we have now. I thought the premise of Kamar was ridiculous, both for a ruling monarch and for Namor. And I couldn't see Namor being anywhere near as ruthless as he is portrayed in the series, especially with Kamar.
Are you asking what happened to Kamar?
Other than that, I thought the series was pretty good. It highlighted the political side of Namor and Atlantis and was like a tour of the MU, and gave you an idea of how Namor interacted with it. It had some great Namor brawling moments and some snarky Namor, also. Loved the art!
Despite my personal misgivings, I usually recommend this for modern comics readers who are interested in checking out a Namor book.
