Bran I
He was in the godswood alone, Samwell was busy looking through his books. They were both concentrated on finding ways to defeat the army of the dead. He took a look at Arya who was crouching and taking a look inside the pond, he then had an idea, and touched the godswood.
He wasn't in Winterfell anymore, or in Westeros, he was in Essos, more specifically in Valyria. He was walking in the streets of the most magnificent city ever built among the people, with dragons flying overhead. He roamed around the city, mostly of Citizens and slaves. It was easy to tell them apart, those who weren't slaves had silver hair and weren't magically possessed.
The stories about Old Valyria were true he thought, looking at all the magic present. But he then returned to his purpose here. There was a large red building, not the largest of the city, but it was odd, as it was located near a volcano. He approached it and saw slaves carrying veins of minerals. A mineral he recognized as Dragonglass. They were all bringing the dragonglass inside. The building itself was quite silent, though he heard the sound of metal being smashed. He then headed towards the sound, which led him to a forge, a man was working there. He wasn't making any kind of steel, Bran knew that. And he knew he had found what he was looking for.
