I've been seeing people post their NiGHTS OC's here, so I'm gonna give it a go.
I actually have multiple OC's, but I'm going to talk about my most developed OC. My nightopian named Prism (who I was inspired after seeing @squiderdoodle OC Void, shes really great!)
Before I show her picture (drawn by @marshmallow-biscuit-blog, thank you very much!) Shes not a regular nightopian. If anyone remembers my first NiGHTS into Dreans headcannon post, I said that I have a headcannon that nightopians have their own subspecies like the nightmaren, with the humanoids being referred as celestials (I'm still debating on whether or not to call them that, but I'm leaning more towards that name due to the fact I imagine their all solar based).
Ok, without further ado, heres Prism!
(The only thing you cant see in the pic is how long her hair is (down to her ankles) and her white ballet shoes (the kind with the ribbons you tie around your legs)) This is what I imagine her NiD look to be, but I'm still trying to figure out what her JoD look would be.
The celestials were once high in number, acting out as guardians of the night dimension. However, after Wizeman died in a coma and his soul still remained in the dimension, he started his goal to take over the very place he was trapped in. Once he started gaining power, the celestials first tried to reason with him, but by then he found a way to consume others' energy, and started killing off the celestial species to gain their power (thats how he gained his godlike powers).
As he created more and more nightmaren to steal more and more ideya, the night dimension itself had started creating a new celestial (I cant remember if I've already mentioned it, but I imagine the night dimension to be alive, more so then our own earth). This new celestial was Prism. However, she was created in a secluded area in a Nightopia, so no one had really been able to find her. It wasn't until an awakener who would later become her friend found her and brought her to Owl, who then raised her and taught her everything she needed to know about her world.
She was relatively happy, she made quick friends with the normal nightopians, she saw Owl as a father figure, and she was safe and happy in her home at the Dreamgate. However, around the time she came of age, she encountered a nightmaren for the first time in her life, while they were terrorizing visitors and stealing ideya. After that day, she had decided to become a guardian of the night dimension, just like her ancestors, and protect Nightopia and visitors.
She was powerful to fight against third levels with no problem and second levels easily after she got used to them. As such, Wizeman decided to create the two first levels NiGHTS and Reala. Now those two, since they were made to be far more powerful then a second level, turned out to be quite difficult for Prism to fight against. The most she could do was provide a distraction for them while any visitors or nightopians in the area could get away.
Due to her experiences, Prism had started believing that nightmaren were a inherently evil species. Even though Owl tried to teach her to not think that way, it was hard for her to see the nightmaren as anything but evil. Until NiGHTS rebelled that is.
Of course, she didnt trust them at first, always keeping a close eye on them. But as they proved that they really had a change of heart, Prism started trusting them more and more. Soon enough, the nightopian had actually befriended the rebellious nightmaren, and finally learned what Owl was trying to teach her. Now, she wishes to try and protect all of the night dimension, not just Nightopia.
Now with her backstory done, here are some random facts about her.
She is 4'7, even though shes an adult (I headcannon all nightopians, from the animals to the pixies to the celestials, to be small in comparison to the nightmaren)
Prism is very naive, not in the 'everyone is good' way, but in the fact that she can take things at face value (like how she saw the nightmaren before NiGHTS rebelled). However, she is always willing to learn, and is more than willing to admit her mistakes and will do her best to make them right. She is also a very kind hearted person and would protect and care for her loved ones (family, friends, etc). As such, she can be seen as innocent at times.
As you can see, her wings dont look like a normal nightopians' wings. I imagine humanoid nightopians have more like dragonfly wings rather then butterfly wings.
She is a very sweet person, but she does have a temper. It can take alot to make her lose her temper (or only a little, depending on what is making her angry) but when she loses it, she proves just how loud tiny people get. She can also be very stubborn when she wants to be.
She is also much more of a 'by the book' sort of person then NiGHTS is. It's why they compliment each other well, she helps them be more serious, and they help her be more playful (that's not to say she doesnt know how to have fun, she often plays with the nightopians when she has free time. But she takes her job very seriously, and can often times come off as a workaholic. So NiGHTS is able to help her relax when she needs it.)
The reason why she was named Prism is because of her light based powers: She can summon light, and can even use this to her advantage when fighting for both offense and defense, but she can not actually bend light itself. Her colors will also change depending on her mood/mental state (her colors will look brighter when happy, they will look drained when depressed, etc). If you look at her appearance, you'll notice that she actually looks like the sky, (sky blue eyes, sun hair, etc).
She has her own invisible instrument! A tambourine! She also she enjoys singing and dancing. Especially when it's a celebration of some sort (I'd compare her voice to Miss Acacia from Jack and the Cukoo Clock Heart, especially in the song 'Flames with Glasses'). She also loves reading, and could spend hours going through her favorite pieces of literature.
She us a very upbeat and positive person, despite picking up on some of Owl's anxious habits (like overthinking things). She has a very high energy and is very sociable, but she always makes sure to focus on her work.
Since the night dimension itself created her, she feels at home when shes outdoors, especially in woodlands or fields, almost as if she feels a connection with the world (she cant communicate with the dimension though, she just loves the outdoors)
The awakener that found her is really small, small enough to hide in her shoulder. His name is Peonie, and he is really shy and a bit of a scaredy cat, but he is protective of Prism and will often accompany her on her patrols or outings when he's not doing his own duties, despite the risk of running into a nightmaren.
And that's Prism! Please let me know what you think! Constructive criticism and questions are always welcome!
