I kind of thought of all the people in the world, you'd have every TSR published Forgotten Realms book ever put out lol…I say that because @Wizards has ruined it by using it to explain DnD changes; or at least that's how I feel.

TSR did the same. The Time of Troubles brought 2e, and with it changes to the Realms. It happened under TSR too, not just WOTC. Also while I may be mistaken; I am of the understanding that before the company was sold to WoC, TSR series were not DnD canon per say, meaning that DnD publishers CHOSE to follow those series as canon, not vice versa, like it seems WoC is doing since they bought it alllll

TSR bought the already-existing Realms to be the "home setting" for the 2nd Edition of D&D, and it was understood by staff and freelance designers that everything we did in the Realms was canon for the game, and vice versa.
