It's nice to get more snippets of Corvos lore, as we likely won't be back there for some time. The reference to Allag and the forced relocation of conquered peoples likely indicates that no one faction can claim 'true' ancestry to the region for themselves.

It's curious that the Garleans under Emet's leadership weren't satisfied with taking the land and brutally subjugating the people as they did with so many other nations, and instead tried to deliberately and systematically erase all traces of Corvosi heritage and culture from the history books. So much for 'Remember that we once lived.'

I think the many food references that we've seen across 6.x are actually nod to forum culture. I'm sure that somewhere out there, the writers are chuckling over the reactions.
