Scrum Witch
The boss of Scrum Office, and the leader of the ritual of Scrum. She advises Thor and regularly urges him to attend the meetings. She occasionally reads him passages of the Scripture.
Technical explanation
The scrum witch is a meme created by chat members who used a voice persona with a witch-like voice for the text-to-speech. Text-to-speech at the time had the technology to have many voice personas. That has later faded away as Thor changes his TTS system over time to ensure that his TTS system works on a massive growth community, and not to mention the many issues that the old TTS system had, which forced Thor to change his TTS system for good.
Chat at the time when the old TTS system existed was using the voice persona that later become known as Scrum Witch, and it was primarily used for office space memes and corporate meeting memes. The primary voice persona was known as Brian.
