A fairly quick question:
The Talastarings were contacted by the Unity Council around 100 after the Dawn, and maintained relations/joined them after that.
They seem to have organized from nine clans to nine tribes?
I am not sure if this means that this was the first time they had contact, or whether they had previously been contacted by Lightbringer missionaries.
We are also told (by @Jeff if I remember correctly) that the Talastarings fared a lot worse than the Heortlings in the Darkness and did not have any significant survival legends/secrets of their own. In practice, this meant that they took in much of the Lightbringer missions' teachings and effectively became Heortlings.
What I am wonder is if what the Talastarings were before the Greater Darkness battered them so low. Were they the last remnant of one of the Vingkotling tribes Are they the amalgamation of the last remnants of several Vingkotling tribes?
This seems to me to be the simplest answer, however the map of settlements of the Dawn Age in the Book of Heortling Mythology places them borth of the Penenthelli and the Berenethtelli, which appear to me to be the northernmost actual Vingkotlings. It also means that these tribes were still around, and not battered so badly they ceased to exist.
There are arguably Orlanthi even further north, such as the Sylilans (BoHM calls them Sylilings, but same things, I assume), just south of Alkoth, and as far as I know, they are a kind of Storm people devoted to Odayla. I am not sure if they were ever considered a part of the Vingkotling confederation/ethnicity, although there are Heortling myths that state that Odayla was a Thunder Brother, and was granted Sylila by Orlanth, so it would at least seem like they were part of a common cultural area, if nothing else. (Not necessarily in the sense that this myth is literally true, but at least in the sense that Odayla was significant enough for southern Vingkotlings/Heortlings to regularly feature him in their stories, and mention his homeland by name.)
So... yeah... them Talastarings, eh?
(Answers for other Storm Belt peoples is also welcome, but please keep it specific, as I am woefully uncertain about a lot of the Pelorian Orlanthi, such as Brolia, Charg, etc.)
