Leendert Hasenbosch’s Tent

Origin
Leendert Hasenbosch was a Dutch employee of the Dutch East India Company who was set ashore as a castaway on uninhabited Ascension Island in the South Atlantic Ocean as a punishment for sodomy. During his time as a castaway, Hasenbosch kept a diary. He began with a tent, a month's-worth of water, some seeds, instruments, prayer books, clothing and writing materials. He searched the barren island for water. Unable to find any, he began drinking the blood of green turtles and seabirds, as well as his own urine. He likely died of thirst after about six months

Effects
The tent causes extreme thirst when entered. Liquids will seem to have no effect at quenching their thirst, which is quickly sweated out. The user will eventually succumb to the effects of dehydration.
