The power struggle between mortals and immortals is also a theme. Mortals may try to gain power or defy the gods, while the gods use their 'heavenly powers' (like the concept of 'fire from heaven') to keep mortals in check. This can be seen in many Greek and Roman myth - based ancient history novels.
Fate is another theme. The idea that events are pre - determined, much like a 'fire from heaven' is something sent from above, is prevalent. In ancient history novels, characters often struggle against their fated destinies. In 'Oedipus Rex', his fate is set from the start, and his attempts to avoid it lead to his downfall.
A lesser - known but interesting 'fire from heaven' - related ancient history novel might be 'The Firebrand' by Marion Zimmer Bradley. It retells the story of the Trojan War from the perspective of Kassandra, a princess and prophetess. The presence of the gods and their influence, like a 'fire from heaven', is a significant aspect of the narrative.
One common theme is destruction and rebirth. Fire often represents destruction in these novels, but from that destruction, characters or society may experience a form of rebirth. For example, in 'Fahrenheit 451', the burning of books is a form of destruction, but later there is a hope for a new beginning with the preservation of knowledge.
One common theme is a sense of renewal. People often come back with a new perspective on life, like seeing the beauty in simple things. Another theme can be a spiritual awakening, feeling closer to a higher power. Also, there might be a theme of unfinished business, where they feel they have things to do on Earth still.
One of the common themes is the struggle against darkness. Fire mages are often depicted as beacons of light in a world threatened by evil forces. Their fire magic is used to fight off demons or other dark entities. Also, friendship and loyalty play a role. They make friends along the way who help them in their journey and they have to be loyal to those relationships while also dealing with their own power as fire mages. This creates a lot of interesting character dynamics in the stories.
One common theme is redemption. Harry saving Draco can be seen as Draco getting a second chance, especially if he was in a situation related to his past wrongdoings. It gives him a chance to change.
One common theme could be power struggle. Since it involves stealing star fire from Robin, there's likely a battle of strength and influence. Another theme might be betrayal, as stealing from someone implies a certain level of disloyalty.
Often, themes like determination, friendship, and sacrifice are common. Characters might struggle but keep going with a strong will.
A common theme is the exploration of different cultures. For example, in fanfics set in ancient Rome, it's about understanding Roman values, like honor and loyalty. Another theme is the interaction with historical figures. In stories set in ancient Greece, the main character might meet Aristotle or Alexander the Great.
One common theme is likely to be the rise and fall of the Tygarian empires. Novels often focus on the growth of powerful kingdoms, their achievements, and then how they crumbled due to various factors like wars, internal disputes, or natural disasters.
Power and its control. The demesne priest of fire has great power, and often the story will revolve around how they use or misuse it.
