Mega structure im building
currently its 1500 blocks long and wide, goes from the bedrock to just under the skybox

each part of this structure had to be built separately and imported as schematics all in all this took me 4 weeks to make and its not done yet! i will be adding more when i get more time.
the structure is in the middle of the map with a long ass tunnel going to the biomes at the end of the complex the train to take you down the tunnel takes 3 mins ish
to walk around the inside of the complex in a circle takes 7 mins

warning: the main area right outside the door is a massive mob spawn ground if not on peaceful
there is a chest full of arrows in side trust me your gonna need them...........

the texture pack in this is still under construction and will b released at the same time as this world save as well as the schematics pack for the individual parts
the tex pack will be called Disease Craft (the green lines in the pics are glowstone) looks mad at night so does the nether
