Ah hello there. If you're reading this you must be getting ready to explore the vast rooms of the lobby. You have your equipment, items, and whatever else you have to back you up.

But you've realized something important. You have no idea what to expect! What's out there beyond the room you've been born/reincarnated/put in ?

Well you're in luck for this book which has been made mandatory across all rooms in the sectors controlled by the "good" factions is here to help.

The first thing all adventurers need to know is simple. Every single room in the lobby is unique. Whether that be because of it's looks, what's inside it, it's size, the rules it follows, etc.

Such is the variety of the rooms that entire worlds inside a room isn't a rarity. In fact  if you're reading this you've probably been born/reincarnated/put in one yourself!

However a lot of the rooms can be summed up into different categories. These categories however are only the tip of the iceberg and are only meant to give you some idea on what you're dealing with. 

More specific and important room types will be shown later in the book.

Room type name: empty.

Description: 

Exactly as its name suggests these rooms are plain and empty. However do not let that trick you. Some of these seemingly empty rooms have nasty surprises for the unwary. Such as but not limited to: increased gravity, time dilation, causing insanity, spawning monsters endlessly to kill you, and more. 

However do not fret for there are just as many surprising good effects as there are bad. A good example of this is the accurately named "alpha" room. A world sized room where no one can die of natural causes nor battle.

Rarity of this type: common
