A man name Sefakiest loved and always supported her research. He killed himself in despair after turned into a mutant; she wanted him to use her as his test subject.

Then one day, someone set the laboratory on fire, which completely burned down the building. and Zid were able to escape before they were discovered and settled in a cave north of Einbroch as they couldn't coexist with Normans.
