The inner critic, the archetypes, the roommate, the voices in our heads, the dark side - we all heard about these topics in their many shapes and forms. 
 
So this event was designed to help us connect with these parts of our personality, may they be on the light side or on the dark side and befriend them. 
 
What happens is that:
 we get to know who's running the show, so that we can take back control and run it in our best interest. 
We think about them, we label them and we give them a shape or form from the real world: a playful child, a judge, a nun, an archangel, a business person, a working horse, a loyal dog, a bully child, a selfish prick, a hedonistic dark lord. 
Whatever it is, we name it. This way we can listen to them, inquire the reason why they are present, what they have to say, why they are so vocal and so on.
 
As a result, you can think of yourself in the future as a master puppeteer. And according to the situation you will find yourself in, you can bring out the most powerful and useful part of your personality: a sweet playful child, an assertive dark lord, a protective queen or a skilled magician.
