The entrance is finallay installed and this prject is complete. However, if there is a problem, feel free to comment about any problems OTHER THAN HOSTILE MOB SPAWN. (there is no gaurentee of hostile mob spawn, but do not be surprised if a hostile is found in the mushroom section. This can only b placed in the nether if you want the nether wart to grow. If the plants are still not growing, then the light is not above 8. Please let me know if this happens; it will be fixed immidiatly.)

Be warned that the only way to get end stone is by mining it with a silk-touch tool. Dont destroy the structure unless you are willing to replace end stone.
