Grian Empire

The Empire was created by Grian near the beginning of the server. The Empire started in has base, some distance away from the original world spawn. He built a railway system to it so that he could travel between spawn and his base much quicker than walking.

The Train Station
Grian started the train station very early on in his series, mainly as a way to get back to his base whenever he dies, especially because there were originally no beds in the game.

Grian's Base
The bulk of the Empire is made up of Grian's base. His base is sunken into the water, and was built out of mostly snow and clay blocks. It has a mob farm, an explosive testing room, and his castle.

Downtown Evo
Grian and Systemzee worked on Downtown Evo together. Downtown Evo was a section of spawn which was built to look like a city-scape, with large, very tall buildings built very close together.

Taurtis
Taurtis's first mention of the Evo server was in Grian's third episode, where he built a "Taurtis Summoning Platform".

On Grian's thirteenth episode, Taurtis was finally successfully "summoned" to the server, and joined the server as a new member of the Grian Empire. He later left the Grian Empire to form his own empire, known as the "Taurtis Republic".

PearlescentMoon
Pearl also joined the Grian Empire. She joined the server much later, and Grian eventually invited her to join the Empire a few episodes into her series.
