@Ian Seamus if i remember correctly the reason for mc's mother running away was that her fathers mind was clouded or smth like he was always angry or smth an after reaching the last stage of sword his mind finally came to the right path and he is spoiling his grandson as he feels guilt for what happened to his mother and also the fact the mother had to break her core to run away so she couldnt save her husband or mcs older sister and the soilders of zeighart were also late so mcs father and older sister died so granpa is in too much guilt for it
