Architect, that you wonder how tall a building can be built, i have to tell you a story which is passed down generations, so you better never try to undertake such an endeavour:

• And the whole elyria was of one language, and of one speech.
• And it came to pass, as they journeyed, that they found a plain in the south; and they dwelt there.
• And they said one to another, Go to, let us make cinder, and burn it throughly. And they had cinder concrete for stone, and slime had they for morter.
• And they said, Go to, let us build us a city and a tower, whose top may reach unto haven; and let us make us a name.
• And The Creator came down to see the city and the tower, which the children of mann builded.
• And The Creator said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do.
• Go to, let us go down, and there confound their language, that they may not understand one another's speech.
• So The Creator scattered them abroad from thence upon the face of all the elyria: and they left off to build the tower.
