At first, Legolas could be defensive. He might feel that the fellowship will treat him differently now. But as they show acceptance, he could gradually open up more about his life as a prince. He might share stories of his elven kingdom, its beauty and its traditions. And he would probably become more determined to uphold the honor of his title while still being a loyal member of the fellowship, using his position to help the group in any way he can, whether it's through his combat skills which might be enhanced by his royal training or his knowledge of elven lore.
One great fanfic is 'The Bond Beyond Rivendell'. It beautifully depicts Aragorn and Legolas' friendship as they face numerous challenges in Middle - earth together. Their unwavering loyalty to each other is shown through various battles and adventures. It also delves into their personal conversations, revealing a deep understanding and respect between them.
Family is a common theme. Given their father - son relationship, many fanfics explore how they interact as family members, the love, respect, and sometimes the misunderstandings within the family.
In the official lore of both 'Harry Potter' and 'The Lord of the Rings' (where Legolas is from), this is completely impossible as they belong to different fictional universes. However, in the world of fanfiction, anything goes. Writers can create an alternate reality where magic systems cross over and such a relationship can be made to exist. It might require some really creative world - building to make it believable, but it can be a really interesting concept to explore.
A common theme is adventure. Since Legolas is often involved in various quests in Middle - earth, the fanfics usually have the reader joining him on these adventures, like exploring ancient forests or fighting against orcs. Another theme is the cultural differences. The reader, usually being a human or from a different race, has to navigate the elven culture that Legolas is a part of.
In many of these fanfics, the theme of discovery is there. They discover not only each other but also themselves. Legolas might discover a new side of himself through his love for someone. Also, the theme of nature is common as Legolas has a deep connection to nature, and it often plays a role in the development of their relationship, like meeting in a special grove or by a magical stream.
Friendship is a common theme. Legolas and Aragorn have a strong bond in the original story, and fanfics often expand on that. Another theme is loyalty, as they are both loyal to the fellowship and to each other.
It's hard to say. Legolas has elven endurance, but Gimli is a dwarf and they are known for their ability to hold their liquor. Maybe Gimli would win as dwarves are often associated with a love for strong ale and hearty drinking.
The plot might involve them using their different cultures' drinking traditions in the game. For example, Legolas could introduce some elven mead - related rules while Gimli might have dwarven ale - based ones. As they play, they could start sharing stories from their adventures, leading to a deeper understanding and friendship between the two.
