Hi guys! Random question, how big do you think the average Dalish clan is? Origins has them looking pretty small, but DA2s endless swarms of bloodthirsty elves has me reconsidering the size. Not that the games are very good representations of size for anything, so it's more of an opinion question.
I would think they have more than a dozen members but probably not in the hundreds, unless the clan is relatively stationary and/or capable of doing some major trading (i.e. artisan craftworks exchanged for various goods, some of which will be used to craft more such works).
A clan needs to be big enough that people can intermarry within said clan without being concerned about inbreeding (although I am sure that clan member trading happens at the Arlathvhen). It also needs to have enough members to defend itself from potential attackers, and to have people in various important survival roles (you'll need herbalists/healers, 2-3 mages for Keeper and Keeper's First and Second, hunters, guards, halla keepers, various crafters and artisans, possibly someone to manage supplies and make sure no one gets more than their share, etc.)
But it also needs to be small enough that it is mobile and capable of fleeing when necessary--unless of course, it's one of those clans that doesn't actually travel much. But that's extremely rare, especially since the Dalish seem to go where the halla take them. (I find that odd, too, because unless halla are sentient--and I kind of suspect they are but many would disagree with me--the fact that they are never told where to go suggests that they know when and where to go for the Arlathvhen. Unless I've totally misread various codex entries and they actually are directed.)
So... My guess? Somewhere between 30-100 members, with each clan different depending on what sort of terrain they travel, the specific hardships that clan faces, and the general culture of that clan. If the clan is fairly stationary, you might get over 100 people. But remember that blood is traded between clans, and some clans allow city elves, especially mages, into their clans to add fresh blood, with varying degrees of welcome. Thus even a small 30-member clan (or fewer) can remain viable, as long as there are enough teen and adult clan members available to do the work to keep everyone alive. A clan under heavy threat from humans or other possible enemies might stay small in order to avoid detection--and because clan members frequently die due to attacks. A raider clan might also remain small. A clan like Lavellan that is relatively friendly toward the humans in the territory it wanders might have more members--especially if they do a lot of trading. Also, you'd find fewer clan members in a region that has fewer potential resources for food, clothing and weaponry. You can't have more people than you can reasonably keep alive
