They did look like Klingons. I wish we got a better lit look at them, though. It seems a natural progression, especially since the makeup hasn't been "seen" since 2005. Not sure I dug the bedazzled ridges, though. Seemed a little odd.
As well, given that we had Augment-Klingons and Kiss-Klingons, it's not too far off the mark to imagine these guys are another off-shoot/ethnic group/race of Klingons.
They may be a bit more tribal in their attitudes. A lot of tribes like having jewelry, mainly in noses and ears, but if you have a head full of ridges, that just seems ripe for the bedazzling.
Not quite on topic, but no other good thread for this. I enjoyed the little nod to Martok with the Ketha Province.
Yep, that was a nice nod.
