Brobdingnag is a peninsula that juts from California into the Pacific Ocean and inhabited by giants. Lemuel Gulliver discovered Brobdingnag during his travels.
It is also believed that Brobdingnag is the birthplace of the fabled lumberjack Paul Bunyan and his celebrated blue ox, Babe.
Brobdingnag was created by Jonathan Swift and appears in Gulliver's Travels (1735).
A popular theory speculates that the peninsula described in Swift's book matches the description of the Olympic Peninsula in Washington State. This, however, does not appear to be the case in the world of the League.
