Mr Sideney
Background
Sideney is a student wizard at the Unseen University in Ankh-Morpork, on Discworld. His greatest fear is the scissor man.
During the events of Terry Pratchett's Hogfather (2006) played by Nigel Planer
Teatime has a meeting with Medium Dave, Banjo, Chickenwire and Mr Sideney. Mr Brown shows up at the meeting and Teatime punches Banjo in the mouth, knocking out one of his teeth. As Violet collects Banjo's tooth she is grabbed, while Teatime hijacks Ernie's carriage. Banjo carries Violet and puts her in Ernie's carriage and the others get inside. Banjo reminds Medium Dave that their mom told them not to hit girls. Teatime then tells Ernie to drive to the Unseen University.
Ernie drives the carriage to a wall behind the Unseen University and Teatime takes some magic powder that Ernie has and throws it at the wall and a portal forms. Teatime then kills Ernie and drives the carriage through the portal. Teatime and the others walk into the Tooth Fairy's castle and some Toothguards stick their heads out from behind pillars and look at them. Teatime tells Chickenwire and Medium Dave to pile all the teeth into a pile and tells Mr Brown to unlock every door in the castle. Teatime asks Mr Sideney if he has any friends and then tells him, he doesn't have many friends, but also doesn't have any enemies. Medium Dave and Chickenwire finish gathering all of the teeth and Mr Sideney starts to cast his spell. As teeth start to fly out of the teeth pile, Mr Sideney tells Teatime there are random bits of belief affecting the spell. Mr Sideney gets the last door unlocked and Teatime tells him he can leave. While leaving, Mr Sideney is attacked by what he thinks is the scissor man and dies of fright.
