Skench is a Great Horned Owl who is a recurring antagonist in the Guardians of Ga'Hoole books The Capture, The Siege and The Burning.
She was the Ablah General St. Aegolius Academy for Orphan Owls (known as St. Aggie's for short). Not having much knowledge herself, Skench relies on moonblinked owls to make her feel smarter than she really is. Her second-in-command was Spoorn and had two lieutenants named Jatt and Jutt and was responsible for killing Grimble (who was falsely working for the academy) who helped Soren and Gylfie escape from the academy.
Soren, Gylfie and the chaw of chaws later return to St. Aggie's to find out if the Pure Ones had sent spies there. Skench suspected this and was convinced when a chaw of chaws member named Twilight made a speech about humble servants, but she let them join St. Aggie's. Skench along with the other St. Aggie's owls took part in a fight with the chaw of chaws and the Pure One spies. Skench later killed some St. Aggie's owls who were trying to discover the power of flecks and smuggled them to make into weapons.
Skench along with Spoorn came to the Great Ga'Hoole Tree to seek refuge with the Guardians after the fall of St. Aggie's to which the Guardians accepted despite Soren's inner protest. Soren refused to teach the two how to fight with fire. During the invasion of St. Aggie's, the Guardians didn't trust Skench, which proved true when she turned against them. But during the attempt, Skench was killed by Soren who struck her with a burning branch and knocked her into a forest fire.
Skench doesn't appear in the 2010 film Legend of the Guardians: The Owls of Ga'Hoole and is instead replaced by Nyra who serves as the academy's Ablah General and trains Tytos into becoming soldiers for the Pure Ones.
- In the Portuguese adaption of the books, Skench is referred to as male. Probably because Skench sounds more like a male name than a female's.
