The Skypiercer

With the schematic of the Skypiercer in our hands, it was time to mass-produce this deadly beauty for my carefully assembled bastioneers. 

But there was a snag in my otherwise flawless plan for the development of this kind of smart-tech weapon.

Fresh water.

Converting metals and Calamity Alloys to create the Neuro Alloy required significant quantities of it, an ironic necessity in a place as twisted and chaotic as Carcosa. 

Freshwater wasn't something we could simply pluck from the ground or a running stream in massive scale, and while I'd briefly entertained using dirt or sand, I quickly discovered that their structural similarity to certain Calamity materials made them incompatible as catalysts. 

There was also a consideration to use the water of the sea if we ever stumbled upon a shore, though we still needed to remove the 'salt' from the 'water' before we could use it as a catalyst.
