Hello again, and welcome back. Now we're getting into the main storyline, and you'll see where this fits on the RWBY timeline before the chapter is over. Hope you have a nice read!

Chapter 4
They had been wandering for hours, Nermina slaying what were apparently called Beowolves and the occasional Ursa Minor, information provided by Amber, with her Heide Knight Sword. Eventually, they had come across a railroad, and while Nermina knew that tracks like these were used for minecarts, she had no idea what a train was before Amber showed her a memory and an explanation, which got her thinking about the technology difference between Remnant and Drangleic, although she hadn't seen the entirety of the old kingdom.
She wasn't convinced that her world would win, if they were to go to war with each other, she was realistic about it. The people of Remnant have an entire career based around unlocking your soul's potential, while scholars back home have trouble truly understanding what the soul exactly is, besides what powers their sorceries and pyromancies, if Nermina were to simplify their findings.
Her thought process was cut off by the sound of metal screeching, and she turned to see a train coming around a turn in the tracks. She now had a plan to get to civilization quicker, but it'll hurt like hell. She quickly cast Resplendent Life and grabbed onto a railing on the train with both arms.
The sheer force felt like it would rip her arms off, but they held, a receding glow over her body confirmed that yes, she had inherited the use of Amber's aura, although it seemed to have a darker undertone to it now. Despite the new information, she still got injured massively, but she had managed to get on the train.
"Are you insane!? You could've lost both your arms! We could've bled out and died!" Amber shouted in her head while silenlty panicking over their injuries.
They had ended up on one of the flat carts that's carrying large containers, full of dust, presumably. As one of Nermina's arms slowly healed, she brought out her Idol's chime and recited Resplendent Life's prayer, accelerating her regeneration some.
"We will... be fine!" Nermina said aloud as she tried to ignore the pain of her broken bones.
"We're out of aura! I can safely say that we won't be fine if security finds us like this!" Amber said in a worried tone.
"You people and your reliance on aura! Back home, we either learned to fight while injured, or we died, aura has made your fighting styles more reckless!" Nermina replied, standing up once her wounds had nealy finished healing, crushing a lifegem to complete the process.
After a few minutes of wandering on the train, the door in front of her was suddenly blown open by the body of a metal golem-err android, followed by a masked man, and a young woman wearing a black bow.
"This... looks pretty bad," Amber said as many other androids added them onto their list of intruders.
"Well..." Nermina started, her Heide Sword drawn along with a pretty inadequate wooden shield, "It could be much worse."
She stood in between a swarm of androids and a probably devastating duo, so she did something that saved her life in the past.
She cast Dark Weapon.
