The Haslanti probably have a legend about their long journey north truting religiously in their Lunar guide travelling to Tzatli to found the city of Diamond Hearth. This story could become legend in it's own right with the Haslanti prepared to trust the tall tale of the Lunar of a fantastical lost city to journey out on to the ice in the hope of reaching this place before winter, then people dying or turning back and the Lunar and the faithful convincing them to carry on and then they find this amazing city and become the founders of Diamond Hearth. Then the tale goes on with how they settled and explored the city and survived the first winter there. The Lunar selected the brave and adaptable Ice Walker tribes to rediscover this lost technology. Since then they have thrived resurrecting the First Age technology they found.
Although the technology of Tzatli kept the Wyld out, the Haslanti and their Lunar guide still had to fight through the dark tunnels against the Fair Folk to reclaim it and during the winters when the Wyld returns.
This sounds like an Icelandic saga but on a much bigger scale.
