So I came up with an another end.
After 5 years, Jon has let his Trag blood flow and built up a strong resentment for the south for pressuring him into killing Dani and exiling him. Drogon comes to the north looking for Jon, sensing his rage. He becomes the embodiment of Aegon the Conqueror reincarnated and wages war on the 7 kingdoms using rebooted children of the Forrest magic.
