Hello there, I'm LordNapstablook, the poor little french student (I'm really small not kidding). I wanted to tell you a bit more things about the Tower.

  First of all I'm sure that you all saw that there are 4 towers and not 1, well the main one is obviously the one with the giant tree inside, the 3 others are the maintenance ones, so they are made to be considered as one large tower.

  Second, for me, the whole facility is the Tower, the ground, the basements, everything is the tower, it's like a Facilitower (I'm proud of this one yeah). I understand that you don't like the idea and you can of course only judge the 4 towers making one but keep in mind that it's a scientific complex, the underground parts are also importants and are an extension of the surface. Do as you wish but yeah ... for me the whole thing is the tower (Otherwise I would have save my time not building it)

  Last, the map cannot be merge with yours, of course you can do it but thanks to that ... not nice commands system in 1.13 relative commands don't work anymore and you will have to replace coordonates in the elevator

Hi, I can see that you arrived in one piece! perfect! So, welcome to the brand new Atllas Corporation Complex, the Facility N°21: LIT Tower.
  You are now in charge of the whole thing, don't disapoint me! As you can see, the complex is linked to land thanks to the magnetic train, it's in fact the only way to come in and out for the moment, we'll add an heliport ... but later. Your role is to keep everything in place while I'm here at Star Valley, you will be my eyes and ears. Your security level is Purple, wich is the second highest but let me remind you the levels: Green > Blue > Purple > Orange.
  Orange is reserved to me and ArC.EuS, Atllas's private AI. Anyway, you will now live here with 4 others scientists, all the other employees are living outside the complex.
I think that's pretty much everythink ... Oh yeah! Try not to destroy the facility, there's a large bank of seeds from all around the world so don't destroy it ... and now that I think of it, the giant tree, you might be curious eh? Well it was created in laboratory and is very precious, its sap is a very conductive substance so you understand that it's usefull for the company.
  Well, I'm done! Ok I have to go ArC.EuS want me to sign some papers ... YEAH I KNOW LEAVE ME ALONE DUMB AI ... damn I'm world's first company's CEO and a robot tells me what to do.. the mic was on? Oops! See you then!
