Mors immedicabilis

Mors immedicabilis was a dangerous disease generally referred to as The Incurable Death. Whole planets have been wiped out by Mors immedicabilis. The disease was fast spreading, causing the swelling of pustules and increasing weakness. The victim were generally dead within minutes. As the name suggests, there was no known cure for the disease. Slarn, whose hypochrondia could cause diseases to manifest in himself, died when he suspected he had it. His Steward also died of the malady. (BBCR: Slipback)
