I'm afraid of what the aftermath will be, with harry potter it was fairly self contained since the ending has a sense of structure and satisfied most, but this? The fucking GOT fandom will now spread to farther lands hoping and searching for their idealized fantasy series and bring all their normie dreck with them. This will be beyond End of Evangelion levels of spergery, this will be something that will try and turn everything in the surrounding area into GOT but with a proper ending and these fools will keep arguing on what constitutes a proper ending.
Build a fucking wall to keep these people out.
