Guardian of the Otherworlders

In a world called "Fanctus", there are a lot of powerful creatures, with the most powerful and oldest among them being the Primordial Beasts, immortal beings who were the ancestors of all creatures alive in Fanctus. One day, one of the primordial beasts, "Serpent Empress" Orphillia, went on a trip around Fanctus, disguised as a young woman, out of boredom. During this trip, Orphillia encountered a young man with a peculiar soul. After journeying with the young man for a while, he reveals that he came from another world, an otherworlder. This intrigues Orphillia, and she asks him to share stories of his home world to her, which she finds entertaining and interesting. But alas, he is but a mortal human, and dies of old age. After his death, Orphillia found herself a new goal, to find and protect the otherworlders, who found their way into Fanctus, and listen to their tales of their home world.

Follow Orphillia on her journey of finding and protecting the otherworlders, a tasks that would earn her the nickname of "Guardian of the Otherworlders" by her fellow primordial beasts.

The story will be seen from the perspective of the otherworlders, who will interact with Orphillia.

This is my first time writing a story like this, so please give me feedback after every chapter, on what I can improve and/or what I should experiment with.
