The Certified Goblin Behaviour Institute (CGBI) is the world's foremost academic body dedicated to the formal study, taxonomic classification, and official certification of goblin behaviour in civilian populations. Founded in 1347 by an anonymous monk who kept eating all the monastery cheese at night, the Institute has since grown into a globally unrecognized authority on the subject.
Our researchers maintain active collaborations with the Innuendo Research Laboratory (whose findings on nocturnal snack-based flirtation rituals have proven invaluable), Brenda's Crystal Emporium (Brenda insists that goblin mode is simply “an unaligned root chakra” and we have agreed to disagree publicly), and the Department of Temporal Affairs (who have confirmed that goblins operate outside conventional time, explaining why 3 AM feels like a reasonable hour for cereal).
The CGBI is not affiliated with any government, though several governments are affiliated with us involuntarily. Our campus occupies the basement of a building that may or may not exist. Fluorescent lighting is mandatory. The vending machine has been classified as a research tool.
