The world of Honkai: Star Rail features a ton of playable characters with each having a specific Path and combat types. Combat types can also be called elements, and they're used to break an enemy's Toughness bar, which puts them in a vulnerable state until their next turn. On the other hand, a character's Path decides their role in a team. These Paths belong to the Aeons of the world, beings with powers superior to anyone else. Herta also has a special program to understand more about these Aeons since people don't know too much about them.
