Deep beneath the surface of Equestria lies an ancient and untouched kingdom. A place no surface-dweller has seen for thousands of years. Even the alicorns of the sun and moon are unaware of its existence.

This kingdom is inaccessible and isolated, leading to a vast and colourful culture completely different to the world above. Once a disastrous encounter with the world above leaves the kingdom wide open, they may just have to abandon their isolationist policies.

Also contains Slice of Life elements, but Fimfiction won't let me have both.
