Known exclusively as either “Sig” or “Siggie,” many students and professors alike have been pecked and clawed by the swarm of ravens that accompany the instructor of all things flora and fauna wherever they go. Markedly, Sig seems to never tire or require rest, allowing them to teach a wide variety of classes, from potions and alchemy to marksmanship. A tall and spindly human with sunken eyes and hollow cheeks, many liken Siggie to a scarecrow, constantly covered in birds and bird droppings.
