The city of Cloudbank...well, you see, it's not entirely resources that are used to construct it. It's not like there are none used at all...buuuut there are certain things that allow it to change so easily without wasting much energy or resources.

I discovered it, you know. The thing that changed everything. Took a long time, very long time...but I discovered the source. That was my personal project after I left my work.
