[@babbysama] I like the concept of a rivalry being ended by marriage. Though perhaps during the medieval period? During pagan times there were really just a bunch of different chiefdoms in Reheba, and a marriage at that time might make one particular chiefdom friendly to those in the south coast of current day Cordonova, but probably not the rest of the chiefdoms, who would probably look at those of the south coast as rivals for siding with this chiefdom.

400 years ago Reheba was united as a feudal kingdom, and the Forentinan religion had taken roots on Reheban soil well before that. Perhaps the marriage takes place then? I'm thinking that such a rivalry would last a long time and evolve after all. If you would like to pursue the idea of doing it during pagan times, I'm sure we could think of something. To me though the medieval period seems to me to be the best option.

Also, I think I'm fond of Reheban.
