So what's it like?
When you open the app, you'll be greeted with the main menu, and from there you can choose to log in with your username and password or continue as a guest.
After that, you'll be able to see all the categories and topics that are available in the app. From there, you can choose to go to a particular topic or category and start reading the information that will help you in your adventure.
You can also find the latest news that's going on in the game, and you can even get a summary of all the events that have taken place so far.
So, what else?
When you're playing the game, you can find the Wiki online, but this app is much easier to use and is updated regularly with the latest changes in the game.
