I love it when LEGO fans fill in the gaps in an existing or discontinued licensed theme. Marcin Otreba decided to create a Fellbeast themselves. Fellbeast are the flying creatures that the Nazgûl rode after being unhorsed at the Ford of Bruinen. The fellbeasts were described as large, winged creatures without feathers, that had pinions in between their horned fingers, and whose bodies gave off a stench. I don’t know if Marcin’s creation smells, but I do know it matches the description perfectly and it even moves!
