As everybody knows, the point (fundamental entity) is capable of infinity. Because of that, when Punctum (Punk, for the friends) got consciousness and scaped from the line, the unidimensional forces felt so threatened that started to chase him using the secrets of the Vertex Wizards. Their goal: to make him come back.
The Bidimensional Allies came to help Punk. They try to protect him from the Unidimensional Forces by creating a protection around him that he should not leave if he wishes to countinue to be free.
