Creating a world is harder than I thought

It is difficult especially from scratch! You have to have immense brainstorming power and your best friend by your side: caramel mocha or that spicy cinnamon flavor chai tea gives you! I've been asking myself questions like: Do you need or even want Animal eared characters? Is there a significant place for them or is it going to be all humans? Not that I'm against nekos or kitsunes, I find them adorable! But do I want to be taken seriously or not? Will including nekos make me look silly? What are the buildings like? How many areas (towns, etc.) are there going to be? How do humans wield magic? That last question is pretty easy to answer, because I am sort of basing my world, world of Wisteria off of Rieza Maxia (tales of Xillia)

Slowly shaping my first ever Fantasy world:

In Rieza Maxia,  people can perform magical moves through mana lobes! They level up and unlock new magical abilities by strengthening their mana lobes! Humans like Elena, Prince Caidan and Princess Rosa and other people in Wisteria will have Element Lobes (Lunar lobes? Need to find a cooler name) which are like the lobes in tales of xillia! I have thought of a few places such as:

Crystal Rose Kingdom:

Its winters are long, but it has all four seasons. Crystal roses spring up during the winter and cold days even rainy ones. Their sparkling petals is the reason behind the kingdom's name! It trades with the other kingdom and has a reputation for having more resources like crystals, its magical/ fantasy animals that roam the rural outskirts of the kingdom, other precious items.

Eltaria Kingdom:

I got the name Eltaria from a fantasy romance novel I recently read, so I don't have the pleasure in claiming I came up with the name first! Eltaria is similar to its neighboring kingdom, Crystal Rose as far as the happy citizens and the seasons. The only differences as of now: Eltaria has longer spring seasons than the Crystal Rose kingdom. It has different resources like various items, flowers, etc. And it is slightly bigger in structure than the other kingdom.

War has divided both kingdoms for centuries and as long as anyone could remember. A solution that pleases both powerful kingdoms, has yet to be made.

The fighting and war had ceased in the past 100 years as both kingdoms had called a momentary era of peace for all. Both sides are tired and need to find a solution before Wisteria falls under greater chaos.

Starlight Town:

A beautiful town where it snows all year round The small glowing snowflakes have a glittering light and are shaped like the stars within the heavens. The snowy rural area outside is immense and has magical monsters. Travelers should be careful when treading across the frozen land. The huge town is filled with smiles despite the harsh conditions. Frosted coated flowers grow wildly everywhere in this cold environment and their scents are just as strong as any flower in the spring.

Four great spirits of Rieza Maxia:

As all who have played the game know, there are four spirit guardians protecting the main character, naturally this has happened a lot in some form of play, book, or movie.

Wind, water, earth, fire Great Spirits!

I'm adapting to that idea and changing it to five great spirits who protect Lady Elena, but won't show up till later. The Goddess's Five serve mainly the one who created them which is obvious on who that is.

This is still a very slow work in progress but so far I think I have some cool ideas and I like them.
