What is the main conflict in The Bloody Crown of Conan by Robert E. Howard?

Conan is a fearless barbarian. He resides over many kingdoms and acquires kingdoms as he goes. Everyone is scared of Conan due to his reputation. Conan will kill and maim if someone talks badly to him or upsets him in any way. He will also kill if someone has done wrong by him. He also has a loyal side. People who help him are rewarded, such as Zenobia, a slave girl who helps him escape imprisonment. He makes her his queen at the end of the story. Conan's loyalty also causes him to kill anyone who is disloyal to either him or his kinsmen. Part of Conan's personality is that he is a brutal warrior with brute strength. He is almost a giant. He has a hulking stature and huge, bulging muscles. He does not look like the Eastern people; he is from the West. He has tan skin, blue eyes and a mane of dark hair. His looks combined with his brute strength allow him to overpower people by just looking at them. They tremble in fear of him.
