You are a new first year wizard going to a magic school called Hogwarts. You buy your supplies and get on a train that takes you to the school. This is where the adventure begins.
Mostly you will adventure the forest or the school for hidden rooms or treasures.
In random rooms or in random places within the forest.
(when I say 'mine' it means a clump of stone mixed with ores)
You will find better mines in the forest. The further you go the more you get lost and the more dangers come(ex. Giant Spiders, soul-less people(zombies), etc...).
However the mines further out are better and have better stuff within.
You mine to earn xp and get items to sell or to upgrade your wand. Also with the xp you can level up to get orbs which you use to learn more spells.
You can also attend classes to get more xp and orbs(when you get an O or O+)
After your 7th year you can become a adult wizard or a professor.
However, more will come.
