The naming basically started while reading Battle Angel Alita and the Sky City Zalem which was held in the sky using a the remaining upper ( actually lower ) portion of a tower that reaches into "nothingness".
Only in the last chapters of the series is it being revealed that Zalem was actually one of two cities being attached to this giant tower with one City ( Zalem ) acting as the counterweight to the other one ( Jeru ) which was being pulled into space - Together they formed Spaceport Ladder JeruZalem.
The tower also acted as an axle for a giant ring rotating around Earth powering the whole thing.
With JeruZalem being the axle on one side of Earth there obviously had to be another one on the other side of it which was ZigGurat appealing more to my naming conventions.
My PC's are basically named ZIG, TEG and HEX with the Windows Work Group they all reside in being GURAT.
