In Blood of Elves, it is reportedly the sort of thing which has been preying on transports on the delta. The Malatius and Grock Company commission Geralt to travel on the transports to ensure that they makes it across, should such a beast attack. And of course, one finally does. After the beast is beaten back and Geralt is safe, Linus Pitt exclaims that Geralt has done him a huge favour by revealing the existence of the beast and that it will henceforth be known as "Geraltia maxiliosa pitti". However, Geralt requests otherwise, to call it "Everetia maxiliosa pitti" instead, after Everett (the future mentally unstable Julius Cudera) who was almost devoured by the monster.
