"The creature was about half a rod tall with bulging eyes and a goat's horns and beard. The mouth, a soft, busy slit, also brought a chewing goat to mind. Its nether regions were covered with long, thick, dark-red hair right down to the cleft hooves. The devil had a long tail ending in a brush-like tassel which wagged energetically." - pg. 176, The Last Wish (UK edition)
Depending on Geralt's actions during the secondary quest Big Game Hunter, Count Beledal may comment that he wants to travel through Dol Blathanna on the way home in hopes of seeing a sylvan. Geralt will then mention Torque to the Count, stating the sylvan "can be mean, but for the right fee he'll do anything you ask."
