Yeah, people in Zonasa have actually said that Kindara looks set to become the new Soliferium.
I say, Soliferium died, and so can Kindara. For now, I'm happy to have them as an ally.
I think the big difference between Soliferum, and Kindara is that in Kindara we have a strong alliance with Zonasa. And Kindara doesn't have Viracocha as judge, that is a big advantage.
Zonasa made lots of friends in Kindara over the support against the attempted Cathayan TO of Edain.
