Another way it can play a role is as a test. Maybe the 'Heart of Gold' has a mind of its own, and it tests those who come near it. It might test Merlin's loyalty to Arthur, his commitment to the good of Camelot, and his control over his magic. If he passes the test, he gets to use its power for good, but if he fails, there could be dire consequences for him and the kingdom.
In fanfiction, Merlin's blood can be a source of great power. It might be used to heal the sick or injured. For instance, when Arthur is mortally wounded, Merlin's blood could have the power to save him.
In Merlin fanfics, Beltane often serves as a backdrop for magical events. It's a time when the veil between the magical and non - magical worlds is thin, so it allows for all sorts of interesting plot developments. For example, Merlin might encounter more powerful magical beings or discover new spells.
Merlin's staff can play a very important role. For example, it could be a key to unlocking ancient magic that has been long forgotten in the Harry Potter universe. Harry might use it to access powerful spells that can help him in his battles against Voldemort or other dark wizards.
His magic would be crucial in safeguarding the baby. If there were any threats from dark magic, Merlin could sense them early on. He could then use his powers to counteract the dark magic, perhaps by creating a magical shield around the baby. Also, if the baby were to be born with some sort of magical ability (since Arthur and Gwen are in a magical world), Merlin could help the baby control and understand its powers as it grows up.
The guard's role is that of a savior. By stopping Merlin from committing suicide, the guard is preventing a tragic end. This shows the guard's sense of responsibility and his value for Merlin's life.
It can be a powerful emotional trigger. When a character plays music from the heart, it can convey their true feelings to other characters. For example, if a character is in love but can't find the words to say it, a heartfelt song might express those emotions better.
Gold often represents power and status in 'Harry Potter' fanfics based on wizarding traditions. For example, wealthy families like the Malfoys have large amounts of gold, which gives them influence in the wizarding world. In fanfics, this can be further explored, such as how they use their gold to gain political favors or access to exclusive magical knowledge.
Religion can play a major role in 'Twilight' fanfiction. It can be used to create new plotlines. For example, if a vampire is seen as a 'demon' in a religious context, it could lead to a story where the vampire tries to prove they are not evil. This gives a different perspective on the vampires in the 'Twilight' universe.
Jashin can also be a source of power in fanfiction. Some characters might be tempted to use Jashin - related powers, which come with a cost. This power - seeking aspect can drive the plot forward as characters make choices between power and morality.
Entropy can play a role in Naruto fanfiction by adding an element of unpredictability. For instance, it can disrupt the normal order of things in the Hidden Leaf Village. Maybe the social hierarchy starts to break down due to entropy, and Naruto has to deal with the resulting chaos.
