She was originally conceived as a joke between Brainy Twilight and I as we thought about what might happen if a jarred kirin brain went nirik, the theory being that the boiling fluid around the brain would burst the jar apart. From there, we just instead came up with a brainless kirin character, and just playing off the humor from there. (Link may contain questionable content, and specifically content relating to brains and modularity.)
I also had a little help fleshing out the backstory from Peachy Claire on F-List. (Link may contain explicit content, including inflation content.)
The image used was a recent commission from FlashEquestria/Space Horse Productions. I plan to post the commissions themselves soon. (This link also contains explicit content. Generally pertaining to massive breasts and related imagery.)
