This floor is home to bla bla bla. Why? Because yadda yadda yadda yadda yadda. Also, it has yabber yabber yabber yabber yabber. It also has yeah yeah yeah in it. Nah nah nah.
Floor 1
This floor looks like an ordinary hotel lobby by day. At night the laws of physics become rather malleable.
This floor possesses a large dimensional gate for travelling to different dimensions. Sometimes monsters tend to accidentally appear from the gate but are usually dealt with swiftly.
This floor is rumoured to hold the cake storage room. However it's all behind a very complex security system so nobody has actually bothered to check if it's true or not.
On the other hand, this floor is the headquarters of Modtek's executives...A quick glance and some talk with the employees revealed that they know nothing about their rival's secret base just a floor below, so shhhhh
Some say this floor has all the relics that were lost in time all over the world... artifacts of ancient and great power... but no one is sure of that... they are hidden...
