Glass dragons, Draco Vitro, are a small tree-dwelling subspecies of Silicate dragons, known for their diet of rocks. They are oft found under pine trees, lured by their tasty fine glass ornaments. Well trained Glass Dragons can be used to hold ornaments for several minutes at a time before crunchily devouring them.
The Great Glass Dragon Uprising of '14 (Not to be confused with The Great Glass Elevator or Gerald's Great Glasses.) was an attempt by the infamous (Or possibly inflamed, sources are unclear.) bubble mage Nycteris The Absent Minded to overthrow world governments and institute a global meritocracy (Where only those with merit badges got perks.) While initially wildly successful, spreading over much of north America in a matter of weeks, it soon met an insurmountable obstacle in the form of the Washington Operatic Society. Her dreams of conquest were literally shattered.
