I have a special activity. Tell me about your OC. Describe them and feel free to share a link of who they are/their outstanding traits. Then describe how your main character (or another character if you wish) would view Macai, the star of Avatar: Macai's Journey (AMJ).
AMJ is a fan spinoff of the original Avatar: The Last Airbender 2005-2008 TV series. It is a Fire Nation centered spinoff. For a basic understanding of Macai, you can read his article on the AMJ or Avatar Wiki
You can look at Macai's Journey on Tapas, but the story has recently been introduced to this platform and is still a work in progress. You can find the completed tale on Webnovel, The Avatar Wiki, Wattpad, and AO3.
An in-depth description of him is in the AMJ and Avatar links above. However, I will offer some basic details here. Macai is a commander who is known for his ability to generate white flames. This young warrior was trained by his father, General Eyre, to become a legendary battle officer. Macai comes up initially being quite dogmatic, loyal, and efficient. He is a tactical mastermind and has a romantic relationship with Princess Azula.
It is not until later in his story, that the Fire Nation noble begins changing his views and having a more open perspective. Even so, Macai has a sense of honor that Azula does not. He is a person of his word and he has a base level of respect for every Human being (though it is a bit higher for those of his nation and even higher for leaders in his society). Much of Macai's philosophy is the result of heavy childhood indoctrination.
