Bren [bren] as a girls' name (also used as boys' name Bren) is of Old Norse, Gaelic and Welsh derivation, and the name Bren means sword; little drop of water; raven or black-haired; hill. Bren is an alternate form of Brenda (Old Norse): related to the English word brand. Bren is also a variant of Brenna (Gaelic).
The origins of the Black Death can be traced back to the Gobi Desert of Mongolia in the 1320s. The cause of this sudden eruption of the plague is not exactly known. From the desert, it spread out in all directions. Of most importance was the spread eastward to China.
Whatever the case might be, the fruits of this backward organization is rotten to the core. The black plague, also known as the black death, is a disease caused by the bacterium Yersinia pestis. It enters the body through the skin and travels via the lymph system. The bacteria live in the digestive tracts of fleas.
