Never let a Dragon dance (смешанная)

Viserys Targaryen went to sleep and did not wake. Then the storm broke and dragons danced.. his House tore itself apart from within, fire and blood became the norm, not just their creed. The end saw dragon fighting dragon until death took them all and they were lost to history and time. They were weakened beyond repair. That was his legacy, a legacy of pain and sadness.
Or was it?
As he lay dying, Viserys is given a choice, a chance to make things right and save his House. Save his daughter and brother from the mistakes he has made, save the Realm from his own blood. But he is only given one chance and he must choose wisely, the gods are not so forgiving a second time.
