Long farewell

The long farewell is a poison originating from Asshai. One single drop making contact with the skin is enough to bring about death. Symptoms include bleeding from the nose, and nausea.

Season 5
Tyene Sand is particularly fond of this substance, and coats her twin daggers in it. During a skirmish in the Water Gardens of Dorne she slices Bronn with one such dagger. Later, after making him beg for it, she gives her the only antidote.
