Shoggoth is an underwater city which serves as the primary point of contact between land-dwelling and sea-dwelling ponies.
Upper Shoggoth Edit
The upper portion of Shoggoth consists of a small island which houses a dock and a monorail/bathysphere connecting to the lower portion.
Lower Shoggoth Edit
The core of the city is located beneath the ocean. I'll fill in the rest of this later because I'm trying to put a baby to sleep
