Description as seen on Tumblr:
Welcome back to Dark Achievement City, located in your local Nether! Here we have:
The Architect – Matt is called as such for his architectural prowess, and the Immortal King goes to him when he has a new project to be built. Though a somewhat solid fighter and sorcerer, he specializes in the creative side of things.
The Scion – Named for his adaptability, Jeremy is an all around jack-of-all-trades. Some say he was born of the Nether itself, and has the unique ability to absorb and redirect magic.
The Shadow Messenger – Kdin is not actually from the Nether, but from the End. With a blessing from the Ender Dragon and wings made of shadows, he is visiting the Immortal King to search for someone who stole power from the Ender Dragon, a heinous crime. He is, perhaps, more accurately known as The Priest?
