Soul Survivor

Our hero - a big guy, cross between Blade and that guy from Witcher 3. Our supporting hero - his dark steed. The story in the dream was like a medieval legend. The hero used to be part of an elite military battalion/group, who were opposed to a corrupt neighbouring kingdom. Location - mountain valley thick with vegetation, a river running through it, and ruins of a castle. A battle took place here. The enemy forces wiped out the battalion, with our hero as the sole survivor. He was devastated and furious and he decided to travel north and to rebuild a stronger fighting force or start a rebellion outright. He watched his enemies celebrate their victory from afar, there was a religious ceremony as well. When he turned to finally leave, a young woman approached him. She lived in a local village, and was sympathetic to the hero's cause. She asked him to take her with him and promised not to be a burden, that she could help him during the journey to a city in the north. He was sceptical at first but she convinced him and they went on their way. The first night they settled down at another ruin, this time by the side of a lake. There were already some women and children sheltering there. The horse drank from the lake and the hero washed his armour and clothes while the lady tried to get to know the others and share food.
