Another theme could be the idea of being swept away. Just as people can be physically swept away by a tsunami or riptide, characters in the fanfiction might be metaphorically swept away by their love. This could involve them being taken out of their comfort zones or into a new world of emotions and experiences. Also, the theme of survival might come up. The characters may have to survive not only the challenges in their relationship but also the literal or symbolic threats of the tsunami and riptide. This could add an element of drama and tension to the story.
One more theme might be the contrast between the chaos of the tsunami and riptide and the order or calm that love can bring. The natural disasters are symbols of disorder, but love can be a force that brings stability. In some fanfiction, the characters might start off in a world full of chaos, represented by the tsunami and riptide, and then find love which helps them to create a more peaceful and harmonious existence. For example, a character living in a coastal area constantly threatened by these natural forces might find love with someone who helps them face and even overcome their fear, and in the process, they both grow and build a better life together.
Survival could be a theme as well. The 'Wings of Fire' world is full of dangers. Tsunami and Riptide might have to fight for their survival together. In fanfiction, this could lead to exciting plotlines where they rely on each other's skills and instincts to stay alive.
