The "Yellow" Plague, was a year long period in Eldar that resulted in the deaths of hundreds of livestock throughout the realm shortly after the mass arrival of Dwarves to Eldar in the Great Dwarven Migration. The plague was dubbed "Yellow" due to the yellow puss that would spew out of animals shortly after their death, which would also emit a horrendous odor. Due to the similarities in time in which the plague occured and the arrival of the Dwarves, many blamed the Dwarves for the start of the plague, which increased further tension between their people and the rest of Eldar.
