Okay that is it from me for the night. I think we touched on a lot of different points. Remember, I have links to a HUGE chunk of lore information in the Dev Post Archives* which is pinned in the General Discussion forum.
Hopefully we will get some more breadcrumbs soon in the months to come. It is kind of a shame that there will be no new major content for Overwatch Archives this year (which should be coming in April), but maybe if we are all good, some teases for Overwatch 2 may come and feed our lore-deprived minds.
*Please note, I am still in a process of restoring dev posts from the old forums into the archives which includes all lore-related dev posts.
