Janus

Janus is a world between the human world and the magic world, hosting the mana tree with 100 great nymphs housing it in total. (They're basically customer service when it comes to warp gates) They also have nymphs (you already knew that), daemons, mana creatures, and spirits. We'll get into the nitty gritty details of the races later, but basically Janus is just a warpgate for most people. It has many cities, often mimicking the human ones but more advanced.   It contains the never ending forest, famous for basically being the gateway to the magic world, connected to snow biomes, water biomes, you name it they have it! Most of the kingdoms of spirits are set up in those gateways, and the great tree nymphs (The nymphs that embody the great mana tree) control the gateway and such.   While we're at it, many of the spirit's adventurers explore the never ending forest (Has to be groups of 20 or more) to map it out for the citizens. So far, Janus hosts forests, lovely beaches, oceans (some with bloodthirsty mana creatures, other with crystal clear beaches), and some habitable areas. Most of the never ending forest has been mapped, but like the ocean, no one really knows how far the never ending forest goes. Some even goes as far to suspect that it ends by going into another dimension altogether.   The technology that Janus has is suprisingly high tech, thank to the magic world. They are a few decades ahead of earth. Low tier spirits tend to live in the human world, although they prefer living somewhere close to Janus, and you can only go to the human world wearing some sort of restrainment jewelry to stop you from using your powers (some low tiers are excused from this). Most of the warp portals are somewhere isolated in a city (Like a cave in a beach) or in lakes or forests.   It generally has a lot of tourism because it's being known as "the rebirth of human and magic tech" or something like that. It has many resorts, cities, things like that. Some areas of the neverending forest literally have no one there because of how dangerous it is, but Janus truly is an interesting place to explore.
