Shrines
Shrines are a special structure and gameplay feature of BetaMC. They are shops of normally unobtainable items like Tall Grass, Fire, Redstone Wire and Diamond Ore. A shrine randomly spawns around the overworld with its location being unknown. There are 24 shrines in total.

The Shriners Project
The Shriners are a group on the server trying to find every shrine, and set up a stargate to them. The diamond block donation shops and the main stargate can be accessed at spawn town to the left of the mall entrance.
Finding Shrines
As the server overworld stops at 50k out from spawn in a square, the shrines are within this 100k x 100k square. When traveling though new terrain, around a 200 block diameter can be seen by the player. This means that around 500 perfect walks are required to find all shrines. There is only around 4.0% chance to find a shrine if you travel like this from one world border to the other, and 2.0% chance if you start from spawn and go to the world border. It's currently unknown if shrines spawn on water or underwater. Maps are basically useless to check what terrain has been generated due to being very buggy.
