In a fanfic, the Dragon Medallion could be a powerful artifact that Azula is hunting. Ty Lee tags along, not fully understanding the danger. Ursa could be a character whose actions in the past set in motion the events related to the medallion. The story could explore the relationship between Azula and Ty Lee as they face challenges related to the medallion, with Ursa's shadowy influence in the background.
A possible plot is that the Dragon Medallion is found by Ty Lee by accident. She tells Azula about it. Ursa is somehow related to the origin of the medallion. The story could then be about how Azula and Ty Lee try to understand the true power of the medallion. Along the way, they learn more about Ursa's past and how she was involved with the medallion. This could lead to a change in Azula's view of power and her relationship with Ty Lee.
One common theme is redemption. For example, Azula might be on a journey to redeem herself after her actions in the original series. Another theme could be friendship, like the bond between Ty Lee and Azula or how Ursa might have influenced the relationships among the characters.
