Berwynne's Gate is an arcology on Berwynne's Reach. Located at the opening of the fertile Highland Valley, the main structure is built between and into two cliffs. The smaller, attached structures incorporate atmospheric conditioners with mixed-use retail space. Berwynne's Gate was originally designed for around 100,000 permanent residents.
Founded in GSC 168 by Ichigo Berwynne to serve as the capitol of the Planetary League colony on Berwynne's Reach, it served as a commercial hub long after the capitol moved to Dunningston.
