Yes. I've completed 10 Viking Settlements so far, and the rewards I've earned add 10 FPs, 10% Attack boost, 6 current age goods, a generous helping of boosted coins and supplies, and smattering of medals to my city every day. Plus each run through gives me 30 FPs along the way.
Daily rewards to your city pretty much max out after 15th run through, but 16+ will always reward 80 FPs and fragments to build more Greater Runestones, basically an SoK on steroids that maxes out at 2 FPs, 2% Attack boost, 1 current age good, and coins.
Boring, yes. Rewarding, big time. Plus each run through takes less time, so it gets a bit less grindy grind each time.
