Dr Walid retains scans and samples of damaged brains.

Hyperthaumaturgical degradation (shortened HTD) is a term to describe the physical damage inflicted on the human brain after extended or intense exposure to magic.[1] The most common exposure event is a user overusing the magic inherent to their own body. However, HTD can also occur from exposure to an intense exterior magical event such as Sequestration. The term HTD, and that of its progressive state hyperthaumaturgical necrosis, are attributed to Dr. Abdul Haqq Walid.

Clinical Manifestation Edit

Dr. Jennifer Vaughan describes the early stages of HTD as consistent with the damage incurred with physical needlesticks to the brain.[2]
