I have little hope that anyone capable of answering those questions will actually ever read this thread, but perhaps at least some of the answers are already somewhere out there and I just never stumbled upon them. Maybe someone can help me out? I have some big problems concerning Dalish lore, not where it touches on the ancient times and accuracy of dalish legends - I mean the way Dalish are in modern-day Thedas as well as some parts of their history after the Dales fell.
So... well, here we go:
1. The problem of tiny halla and other Dalish mounts.
Various sources tell us about Dalish knights (in the Dales) riding Hallas, the latter are also stated to be much bigger than any ordinary hart. There comes Inquisition, howwever, and ridable harts that are much bigger than any halla encountered in game. The hallas we see are, indeed, pretty small to be ridden, even by elves, and the avarels seem much too big to be pulled by halla (unless you use lots of them, really). Is that just a gameplay thing and hallas are supposed to be the size of those harts? How common are hart mounts among Dalish, really? And among other races?
2. The Dalish-Alamarri war/battle and timeline/lifespan question.
In Dalish elf origin (DA:O) we get to learn that the Dalish, after retreating east from destroyed Dales, decided to (or were forced to) fight with local Alamarri. However, the elf we hear of it from is, supposedly, a son of that war's veteran, while we're also told that Zathrian's three hundred year lifespan was perceived as something amazing (until it was revealed to be an effect of blood magic binding him to Lady of the Forest). Is this just a mistake and was any mention about "father" supposed to be rather something about some (much) further removed ancestor at best?
3. The 3-mages rule and extra mages.
There are numerous accounts of Dalish cherishing any sign of magic among their children (as the gift is not as common as it used to be), there are also a couple cases of bringing in additional mages despite having three or more, we also know that Lanaya had a competition for her position as Zathrian's first - so it would imply that the clan actually had a couple other young mages, who apparently got over her being chosen - so it doesn't seem like they got either kicked out into the woods or shipped to other clans. In DA:I however the practice of kicking mages out seems to be in effect, in one case it's apparently done to a seven year old child. Is this practice any more widespread or should we consider it some one-time occurance that generally goes against Dalish ideals?
4. Non-Dalish ironbark crafting.
There are numerous examples of non-dalish craftsmasters working the ironbark. Should we consider it a gameplay thing, or does it simply mean that the material being succesfully used for crafting only by the Dalish is just some myth that has little to do with reality?
5. Scale of Arlathvhen.
It's stated that "the clans gather", but is that really so? From what we know Dalish are quite occupied with surviving and hunting provides them with most of their food. It seems logistically impossible to actually gather all (or most) of the clans in one place every ten years since they would invariably attract attention and they couldn't possibly feed themselves when gathered like that - and then there's the fact that gathering everyone from every corner of the continent seems like another huge logistical problem, such journey for a whole clan would most likely take years in and of itself.
Is it that that in reality only a small portion of clans makes appearance and others send some delegation or ignore the gathering completely? Or could it be that the clans are generally concentrated in the South and there is much fewer of them than it would seem seeing as they (possibly) managed to gather a respectable expeditionary army on short notice in DA:O?
6. How many elves are out there?
This one perhaps concerns city elves more than the Dalish, but how many elves are out there? What percentage of population do they generally constitute? One of elven occupations is stated as "farmhands", so I assume there are quite a lot "city" elves who actually live in the country, working the fields for some measly pay... I guess population of Dalish would be harder to estimate, but that would be interesting too, especially in light of the question about Arlathvhen. They seem to be numerous enough to get somewhat noticed everywhere across the continent (even by guardians in Arbor Wilds who have little to no contact with outside world), but how numerous could they actually be?
I would be thankful if anyone can point me to answers if some of my questions had been answered anywhere, even more thankful - for some new answers... But I guess chances of Bioware staff actually reading this thread aren't big
