The Codex makes no mention of them by all being captured, it's not hard to imagine some escaping capture as it never says they were wiped out.

I agree. At worst you could say it's a grey area, but I don't think it raises any need to make changes.

Also, the word Kossith is no longer used, the people, or 'race' is still very much alive, just known now as Qunari.

There's actually some dispute around this, both due to conflicting in game sources and conflicting statements from writers. Some argue that Kossith is the race and that 'Qunari' refers to anyone who is a follower of the Qun. Some argue that Qunari is the race and that the religious term was named after them; these people often claim Kossith was an outdated term. And some argue that the Kossith were different to the Qun but were closely related, with the Kossith coming from the South and the Qun from the north. [b]Either way[/b] this doesn't make an awful lot of difference to the 'current' setting and doesn't really affect Kathleen being a giantess. I just thought I'd kill this potential debate before it even started :P
