One possible theme could be power. Since it's about a dragon's soul, which is likely to be a powerful entity, the characters might be dealing with the allure and danger of such power.
Another theme could be identity. If the dragon's soul has some sort of sentience or influence, characters might question their own identity in relation to this powerful and otherworldly force. Also, the theme of good vs evil is likely. There could be those who want to use the dragon's soul for benevolent purposes and others for malevolent ones, leading to a struggle between the two sides.
The theme of mystery and discovery is also very likely. The dragon's soul is probably something not fully understood in the world of the novel. Characters would embark on a journey to discover what it is, how it works, and what it means for their world. This could involve exploring ancient lore, forgotten places, and interacting with strange creatures. Along the way, they may also learn more about themselves and the true nature of their world.
