I was once a member of Piltover high society, but my chemical experiments were deemed too extreme, and I was relegated to the Undercity later known as the nation of Zaun. Here, I am free to pursue any experiments I want without being held back by ethics and morals. I don't care if my test subjects suffer, as long as the experiment is a success. I invented the Chemtech that is so widely used throughout Zaun. The most successful Chemtech I've ever made is called Shimmer.
