Title help pls

Okay so I have an idea about what I want the title to be for my book and it is "5 Kingdoms" but I feel that it is too bland. It doesn't give anything away and the book is about alliances and fighting between the five kingdoms but there are also like four groups outside of that so I don't know if that would be a good title.

also, I would like for there to be five to six books in the series so I am trying to think of separate titles for each of the books, and I want it to follow some sort of a pattern. I can figure out titles but if you could give me a pattern idea that would be great!
(I have already tried doing the two opposites but it ended up sounding like Game of Thrones too much, I've thought about each book is the name of one of the kingdoms but I feel like I would have to write in the perspective of that kingdom and I want the main focus to be on only one. I have also tried the names being characters names but I feel like I need to change character perspective and that bothers me.)
maybe just list some adjectives and see if I get any inspiration? Thanks!

What I do when I write books is, I have the name of the main book and add "book one" to the book, and so on. It is entirely up to you what you do. I am simply giving a suggestion.

Name it a view point maybe . I know that sounds weird, but it turns out kind of cool. For example, I have a book I'm working on about a hero, and the first book is called "More Than Mere Humans" because that's what the villain believes. The villain thinks people like him and the hero are the next stage in evolution. Second book is going to be something science based because the villain is a scientist. I think that would work here. Like think of what the goal or mindset of the protagonist or antagonist are. Maybe as simple as "Rule with an iron fist" or something. Just kind of depends on what's going on. Hope this helps!

You could take an object of significance within your story and then couple that with some symbolism that affects the plot. For example, one book I'm writing is titled Twin Mountains (Or The Twin Mountains, I can't decide. Which one sounds better?), based upon a mountain range within my world called "the twin mountain range" and symbolism between two of my main characters (and their ancestors, incidentally) being very parallel in their relationship and fate. The second book of that series is the name of an important character that everyone's trying to find. And then I haven't figured out the third book's title yet. :P

@Masterkey I think in this case using "The" helps for the way the symbolism is portrayed.

Okay thanks Dylan!

There's this Youtuber named Jenna Moreci and she's an amazing help when it comes to… well, anything that has to do with your book writing process and beyond!
I'll attach the link to her video that helps with coming up with titles for your book. This discussion was started March 23rd so I don't know if you still need help with it or not, but oh well!
WARNING: She isn't afraid to use F-Bombs. I'm not sure if this is a problem for you, just throwing that out there in case it matters.
