This Minecraft server is a Minecraft Java server. You will need to own Minecraft: Java Edition on your Microsoft account in order to join.
The requirements for connecting to the server are:For ease of installation, I recommend using Prism Launcher.
Once you download and install Prism Launcher, and sign into your Microsoft account, it is time to add and install an 'instance' of Minecraft with the modpack installed.
In Prism Launcher, click "Add Instance" in the upper left corner:
Click on 'CurseForge' and, in the search bar, search for "Prominence II RPG: Hasturian Era". At the time of writing, the latest version was v3.0.21, but if a new version comes out you may need to change the version to match this.
There are a few mods which Prism Launcher is unable to download automatically. For these three mods, click on the links to open the page in your browser and download them into your "Downloads" folder. Once they are there, Prism Launcher will show "All mods found" and you can click "OK" to proceed.
Now it's time to wait--the rest of the mods will need to be downloaded and installed.
Once the setup is complete, you should be able to 'launch' your new Minecraft instance in Prism Launcher. The game will likely take a while to start up (there are a lot of mods to load). Once the game is started, go to "Multiplayer", and then add the server.
The server address is oldfall734.playat.ch:25565.
