Not only was she traveling with the master, but she also knows he's a judge of the world and is about as powerful as the dragon that exiles Noya back to the world of Peerless dad (the same dragon/man that has a bad temper and challenged Yulian to a fight in the last stage of his warrior challenge). In addition she had a bit of control over the undead King that Noya was using as a work horse and can manipulate people to assist her as needed.
In other words she's pretty important, but her story is spread out in between chapters so it's easy to miss
Check chapters: 94, 97, 101, 115, 131, 145, 155, 156, 172, 178, 179, 185, 186 (there might be a few I'm missing, but that's most of them)
Other related chapters: 162-165 (meeting the dragon the first time during yulian's warrior god test)
Also, finally caught up with this one... now I can just read it as it comes out.
