Comments of chapter undefined of Morningstar House (GOT)

I risk sounding clueless and inattentive but wasn't this a book about an immortal establishing his house and increasing his power in planetos. For me, it's like the mc moved to Winterfell and married a Stark and then the book started focusing on the things around the mc while barely mentioning his actions and development as a passing thought. Please help me if I lost track of the plot somewhere.

gracias por el capitulo
