Steve has fought the might of a 3 headed being of withering, a creature of mass strength that resides in a temple under the oceans, and even a great dragon within another dimension. But now, Steve is faced with a new being, one that he has not seen before. Will he be able to defeat... "The Hollow".

Who or what the skin is:

The Hollow, otherwise known as the Night Monster, is everything a dreamer fears, it thrives on the fear of children, taking a cruel delight in turning their pleasant dreams into nightmares.

It is my imagining of a creature that haunts the closets and dark corners of your nightmares, feeding on your fear to survive. It is with such fear that can allow The Hollow to enter reality. Once it comes, it will bring with it the disease and act as an invisible hostile enemy that only attacks when the character is in complete darkness or unable to see.

What The Hollow hates, is when in rare cases, the dreamer overcomes their fears and don't believe in him, causing The Hollow to cease to exist.

Although few have succumed to The Hollow, it is said that it does not look disimiliar to a plague doctor. The disease itself first appears with symptoms similar to that of the common cold. Unfortunately, within a few days, the disease progresses. It begins with the victim experiecning more night terrors and eventually, they are too afraid to sleep. Due to the insomnia, the victim starts to have temperature fluctuations and hallucinations that force many victims to madness. The complete loss of sleep results in rapid weight loss; dementia and irresponsiveness, followed by a sudden death which leaves their skin cold to the touch. However, their body still acts mindlessly, spreading the disease to others. It is with The Hollow's gear that, in theory, protects it from contamination.

How it relates to the theme of "Boss Battle":

After conquering the other bosses of Minecraft, it is up to the player to defeat what is currently mearly more than a myth and put an end the plague it brings with it. It will be the most difficult challenge Steve has yet to face, and he will have to be strong not just physically, but also mentally, to resist the nightmares in which The Hollow creates for him.
