I realized finally that Nikki sort of has a place in the weird existence in my head.
Nikki was such a useless character for so long. But I remembered how she was basically an interdimensional traveler with no knowledge of what she even is. Well that almost fits in with the new character Kveikur.
You see, Nikki is an anomaly from the Lack (gonna call it that now, the name is sticking). She spawned off of a piece of existence that Kveikur was attempting to ignite.
Oh yeah if you didn't know, Kveikur, while not a god per say, is the catalyst for creating life in the Lack. His existence is to help spark other instances and universes.
Okay back to the point, Nikki spawned off of him by accident. Her sole purpose in life is to cause chaos and mayhem wherever she goes. She'll travel from dimension to dimension, pulling stupid little pranks. If she's left alone in a dimension for too long it'll start to get out of hand and she could even cause complete chaos if left unattended.
Kveikur is not fond of her. About the only person he's not fond of (Kveikur has an deep love of life and living beings), he has to constantly find her and drag her out of out of a world and back into the Lack.
Also the imp with Nikki is another being from the Lack. He's just her little partner in crime. He's not always with her though.
Phew, probably the most backstory on Nikki I've ever provided.
