When I came with the story idea of I'm not a Wizard, I used the names "Eric" and "Solomon" as placeholders until I finally thought up better names. However, I ended up using the names anyway because I thought they sounded fitting.
Solomon was always met to be a female character. But because I didn't want to change Solomon's name, I decide to tinker with Solomon's backstory so her name would make more sense.
Aragore's name went through the same thing with "Eric" and "Solomon" names, it was a place holder until it was not a place holder.
Blair's full name is Blair Juno. In Scottish and Gaelic origin, and the meaning of Blair is "plain, field" and Juno means queen of the heavens in Latin. This is why I gave Blair "golden wheat hair" and an overruling personality.
Ash was the one out of the gorgons with a name that actually represent her magic abilities.
When I was coming up with Onyx's surname, I was a bit stumped. I looked at the name Bayleigh, but it didn't sound provoking enough. I looked at the name Devon, but it was too short. It was then when I put the two names together, I found a name that spoke into my soul. And that's also why I made his magic necromancy.
Mostly everyone else names is from lists of unique unisex names I searched up on the internet.

Odin was another placeholder name before I decide to use it. I was going to change Odin's name to Hephaestus; the Norse god of the blacksmith. But I felt a connection with the name for some reason and stayed with it. That said, it took me a few minutes of writing down Clover to realize that I could leave the name Odin and make Clover and Hiccup his sons, like Thor and Loki.
The name Clover sounded like a small cute name in my head, so I used it. It was also a recommended name for my baby nephew, but he wasn't called that.
It was either Marigold, Sunflower or Dandelion because they are all yellow flowers. I always saw Odin's wife wearing a yellow flower dress. That's why I wanted her to have a name after a yellow name.
Hiccup doesn't need much explanation, because it is obvious that I took this name from "How To Train Your Dragon".

Harry's name is from two things. The name Harry itself was from "Harry Potter". Spode and Minton are from Josiah Spode, Thomas Minton, and, most important, Josiah Wedgwood was among them. His many artistic and business successes showed younger potters and nascent industrialists how to exploit the new markets, means of production, and sources of power that would characterize the coming age.
