That is what I want to do, use Six Ages as "ancestors references", stories, when Heroquesting in the Gods war and bring back "hidden/forgotten truths". Yes, Yelmalio is there and Ernalda... But the chieftain would be Hyalor, maybe a cult similar in structure as waha. I have to convince my GM because is a lot of work for both, so using waha cult as structure and six ages as cultural references (a clan circle of seven families, story tents, genders much more balanced than yelmites...) may work. Things didn't end well for Broyan but he returned with vingkot's tattoo and the helm and sword. This are the Hero Wars, right?
What do you think?
