There are several things I recommend if you destroy Lys. 1 Discovery of some direct descendants of Shaena Targaryen, the last daughter of Jaeharys I, which would be interesting. I would say that they were two little sisters, 10 and 8 years old, and that Rhaella adopts them the moment she sees them, since they remind her of her mother and her aunt, also seeing how motherly she is she is probably like her new mother. 2 Liberation of Serra Blackfyre and end of the Targaryen civil war, this takes place between Rhaella and Serra in secret since Aerys would not allow it, recovery of the Darkfire sword. This has the consequence that the plans of Ilirio and Varys are ruined. Since I doubt that Serra really loved Ilirio, it's more that their relationship seems to me like the forced marriage of Khal Drogo and Daenerys, since I think that Varys (her brother or cousin) sold her to his friend without hesitation. And then he dies in strange circumstances, I suppose so that no one sees the resemblance between Serra and the Young Griffin, since it would be discovered that Elia is not his daughter. 3 Liberation of the last Rogare, who are also family of the Targaryens and recovery of his Valyrian sword.
