A Tulpa forms when a mage becomes one of the Mad. During this process, his soul cracks open and some of the Arcana that are intuitive to him fuse with their Vice to create an effect that is affected by the Mad one’s fault. If he represses this fault, even more Tulpa can form, rending his soul more and more apart. When a Mad falls further from the path of Wisdom, his Tulpa gain strength and strange effects in correspondence with their vice and their fault happen. Tulpa can appear anywhere with a sympathetic connection to the Mad One or another of his Tulpa, which can make them extremely wide-ranging. Some extremely powerful Tulpa even form into spirits that follow the Mad One on their own accord and act on his vice.
