Team RNJR, Nuckelavee Slayers, Fighting against Salems forces.
Team RNJR were trekking through the forests of Anima, on their way to Haven, when a Nevermore swooped down over their heads and fired its feather projectiles at them, though luckily none of them were hit.
"JOOR ZAH FRUL!" A booming shout rang through the forest, as the Nevermore crashed headfirst into the ground, surrounded by blue light, and slid 25 metres down the path, digging into the earth. A figure in black metal armour jumped down from in a tree.
"Honestly wasn't expecting that to work." They muttered, before turning to RNJR. "Are you okay? Just stay here, I'll go kill this thing."
"Wait! You can't kill a Nevermore alone!" Ruby exclaimed, concerned for their saviour.
"I killed Alduin the World-Eater, I can handle myself." The ebony clad figure said before turning around and running towards the downed Nevermore. Blue-purple sparks of electricity danced in the palm of their right hand, and frost and snowflakes swirled around their left hand. They pointed their hands forwards at the Grimm.
"What's he doing? Does he think he can use magic or something?" Ruby asked her team.
"I don't know, but I would like to thank him for saving us." Ren said calmly. Suddenly, huge forks of electricity struck out from the armoured figures left hand and a spear-like icicle flew from their right, killing the Nevermore instantly. RNJR stared at them, jaws dropped so far, they were practically scraping the ground. As the figure started walking back over to them, a small spark of fire appeared in their right hand, and they picked up a branch the Nevermore broke when it crashed. The teens began to back away, afraid that the sorcerer would attack them. The figure pointed their hand at the branch, ignited it, and handed the flaming torch to Ruby.
"You looked cold. Now, if you follow me, I'll take you to my camp." They turned and walked into the forest.
"Wait! Who are you?" Ruby ran to catch up to them.
"My name is Rizu Senshi, and I'm the Dragonborn."
Ren turned to Nora and Jaune, who just shrugged and followed suit. Ren sighed and joined the convoy.
(Meanwhile, with Ruby)
"Howdidyoudothatmagic?whatisyourarmourmadeof?isitdustinfused?doyouhaveanyweapons?" Ruby tried to ask four questions at the same time.
"I don't know I just can, its made of Ebony, its not dust infused, I have this," Rizu drew Dawnbreaker from its scabbard on their hip, the light in its guard illuminating the dark forest. "And this." Rizu pulled out a glass bow.
"Woooooooaaaaaaahhhh..." Ruby looked up at the towering Rizu, eyes full of wonder.
"Anyway, we've arrived." Rizu gestured to a small camp in a clearing. "Make yourselves at home." They said, walking over to the extinguished fire and relighting it with a small spark of fire from their palm. RNJR moved various logs and tree stumps to arrange seats around the fire. Rizu sat on a log facing them, reached up to their ebony helmet, and took it off. Staring back at RNJR was, for starters, a woman (which they did not expect, considering what most huntresses wear. *cough, Yang, cough*) who appeared to be a humanoid cat.
"Wha-...a-are...are y-you a f-faunus?" Ruby barely managed to stutter out, due to shock.
"Of course not. I'm what's called a Khajiit, and I'm not from this world. I'm from a place called Skyrim, where dragons rule the skies, spiders the size of dogs lurk in the darkness, a civil war rages on into the foreseeable future, and the remains of an ancient civilisation hide dangerous artefacts." Rizu explained.
"Wow, sounds dangerous, maybe even more dangerous than Remnant." Ruby said.
"Earlier you said that you were something called a dragon born?" Ren asked, apparently he was the only one who had been listening properly.
"Yes, I am the Dovahkiin, or in your language, Dragonborn. This means that when I kill a dragon, I absorb its soul and unlock its power by learning the ancient words of power. For example...FEIM!" Rizu transformed into her ethereal form for 8 seconds before changing back. "Just then I used the first word of Become Ethereal, which allows me to become ethereal, as the name suggests, making me immune to harm but unable to interact with the physical world."
"Wow." Ruby said.
"You absorb their souls? That's brutal."
"I don't deliberately absorb them, it just happens. Like one time, a dragon began attacking a city called Riften and landed on the orphanage, so I helped the city guard kill it, and once it was dead this white and orange light began swirling around me! I thought I was dying, turned out I was just a living myths and had to climb the tallest mountain in Skyrim to learn about myself from a cult of old people!" Rizu rambled. "I'm...gonna go to bed now...don't kill yourselves in the night." Rizu entered the tent, crawled into her sleeping bag, and drifted to sleep, the soft sound of RNJR's banter and chatting fading away.
