Okay, so in two chapters, we reach 30 chapters in one week or so, excluding the Author's Note (first one and this one)
Now, we can either go till 50 chapters and then start the House of The Dragon fanfic or we can start that fic once we hit 30 chapters.
The fanfic will be a prequel to this one and will be a tie-in and will focus in Aerion Targaryen (OC) the one mentioned in earlier chapters.
Or we can wait till we finish this one, which will take a while and then start it. The choice is yours
