These three seemingly random screenshots are offcuts from the end of the original post of the first tour of this world on 19 January 2015, that didn't fit in any of the other projects.
The Nether Hub - portal coordinates NX +49 : NY +117 : NZ +14
This is going to be far more organised than Rejectland. This room is far, far up in the Nether - the floor is y=116.5, seeing as it's heftily slabbed, and it's right near the bedrock roof. (Remember that breaking through the roof of the Nether is also banned in this world, even though it could still be done when this hub was built.) As I've got so much iron to hand, I'm not making a complicated track selector - each wall of the hub has five individual tracks that go to one specific location, and if that means five lanes all running the same way for several hundred blocks then so be it. The lava pillar in the corner shows where the escape hatch to ground level is - and slime blocks can be used to make a quick way down and not die from fall damage, which was never available before 1.8.
And I really have spent a lot of time in the Nether recently. Wherever there was a portal away from the main hub - at the witch farm, the ice plains I haven't shown you yet (because that's all there is there), the original swamp where I harvested slimeballs... I dug a tunnel downwards and cleared the area around me of any visible Nether quartz. And then, I had to dig a huge tunnel further away (I made it 1 km long just to get the On A Rail achievement at the same time!) to reveal a new Nether area purely for the purpose of quartz mining. The result you can see here... twelve double-chests, all full of quartz. What I will do with it is to be revealed in a later project, which will be an absolute wonder to behold!
Meanwhile, at Open Forum, the chest full of tradeables also contains a lot of emeralds. The 64 blocks and... the rest (which is enough for another 44 blocks) were obtained by selling all the rotten flesh I had accumulated over the course of building the gold part of the Foundry, from the XP farm, and from Horace's Revenge. It's 36-40 pieces of nasty flesh for one emerald, nine emeralds to a block, and that just goes to show how much I had stashed away. As with the quartz, this will also come in handy in a building project in the near future.
