Gargoyle

In architecture, a Gargoyle is a carved stone grotesque with a spout designed to convey water from a roof and away from the side of a building. Several gargoyles can be seen on the Castle of Camelot, these gargoyles were formed in Cornelius Sigan's process of building the city of Camelot.

History
When Cornelius Sigan returned, he used magic to bring the gargoyles to life. The living gargoyles started to attack Camelot and its citizens. Arthur Pendragon and Sir Geraint led the Knights of Camelot in an attack against them. Arthur was nearly killed by a gargoyle twice, but was saved by Merlin one time, and by Guinevere the other. Merlin then confronted and defeated Sigan. After Merlin defeated Sigan, it seemed that all the other gargoyles were returned to their inanimate state (The Curse of Cornelius Sigan).
