The Dungeon Meshi anime typically ends at a specific point in the manga storyline. However, it might vary depending on the adaptation decisions made by the producers.
Well, it depends on personal taste. Some people might find it really engaging as it often involves unique interpretations of the red dragon in the Dungeons & Dragons universe. It can bring fresh adventures and characterizations.
Well, there are several common themes. The first is the red dragon's territorial nature. Fanfics often depict the red dragon fiercely defending its lair. Another theme is the red dragon's intelligence. Many fanfics show the dragon as a cunning and strategic creature. There's also the theme of magic. Since red dragons are magical beings, fanfics may explore the types of magic they possess, how they use it in different situations, and how it affects their interactions with other creatures in the D&D realm.
A worm dungeon in the context of D&D fanfiction could be a really interesting and unique setting. For the mercury dragon, it might have special abilities related to its mercury - like fluidity. Maybe it can seep through small cracks in the dungeon walls, or use its mercury - based breath weapon to corrode metal objects in the dungeon. Fanfiction allows for so much creativity in exploring these concepts.
