Moribund Curse

Officially known as mVirus 476 or colloquially as Moribund, the Moribund Curse is a magic based virus, or mVirus, which uses sapient or semisapient, magical species as the host body. The virus creates a strong link between the host and the universal magic field and then infecting others through magicks used by host. The virus gets its name from the slow decay infected go through, being driven to insanity and being pulled apart by their rapidly growing magical power.

The disease is referred to as a curse because it began as such, but because it was designed to take the form of a magic based virus and it fulfills all of the requirements to be classified as one, it is officially considered to be an artificially created mVirus.

There has never been a large-scale breakout of Moribund as the disease is not highly infectious, rather its danger comes from the wanton destruction caused by hosts of the virus as they try to release the buildup of magickal energy.

Progression
The life cycle of the virus begins with infection, which occurs through contact with the magicks of someone who carries the infection. Once infected, the host is forcibly strong-linked to the  UMF. This is a notably painful process for the host, and will in most cases serve to break them mentally. This prepares them to be exploited by the virus and driven to infect others through reckless use of their new magic powers. The virus encodes itself in the hosts link with the UMF and so automatically includes itself in any majicks used by the host. When the another being capable of hosting the virus comes into contact with the majicks of the original host the virus, the virus transfers itself the the being's link and begins the process again.

Symptoms and Diagnosis
The primary symptom of Moribund is a constant leakage of magical energy from the host as their connection to the UMF becomes stronger to the point that they have no control over their own power.
