When Vainóni and her mother Tirannë fall in with Kurúki, they are given a baneful drink by him, which caused them to forget their names and wander distraught within the woods. Eventually, upon the death of the Foalókë, the dragon lifts the veil that Kurúki placed on Vainóni, causing her to flee through the woods and throwing herself over a waterfall.
Other versions of the legendarium
In later versions of the tale of The Children of Húrin, the character of Kurúki was discarded, giving Glaurung the magician's former role of erasing Nienóri's memory in addition to his own role of breaking the spell of forgetfulness. Interestingly, Christopher Tolkien notes that there is a chance that it is probable that the outline fragment that Kurúki exists within may in fact be a unique glimpse into a draft of the Tale of Turambar that predates that of the erased text which many of the stories found within The Book of Lost Tales were written upon.
