Ethenea is a quest item given to the player by Elena during the Biohazard quest. The player must smuggle it into the gated area in south-eastern Varrock by giving it to Da Vinci, one of the chemist's assistants in Rimmington who will then carry it to The Dancing Donkey Inn. Unlike the sulphuric broline and liquid honey, the ethenea is colourless, meaning Da Vinci will not try to paint with it.
