There's a possibility that the main characters in this fanfiction are characters who have made a pact with some sort of spiritual or elemental force to become eternal guardians. They could be ninjas who have a special connection to nature, like a ninja who has a deep bond with the fire element and is chosen to guard the source of all fire - related jutsu in the Naruto world. Or it could be a group of outcasts who are given this new purpose of being eternal guardians and have to prove themselves worthy in the face of a world that once rejected them.
It depends on the specific fanfiction. It could be Naruto and his friends taking on the role of eternal guardians. Or perhaps some new characters created by the author for this concept.
In some versions of 'naruto eternal guardians fanfiction', the main characters could be descendants of powerful ninja clans who have been entrusted with the eternal guardianship. For example, members of the Uchiha or Hyuga clans might be central characters. They would bring their clan's unique abilities and histories into the role of guardians. It could also be that some previously minor characters are given more importance in this fanfiction and become the main characters as they are chosen to be eternal guardians.
