This is the castle and home base of operations I have built in my Hardcore mode world. Its small and simple but has enough room for storage, bedroom, enchanting etc. It even has a large cave network out back that leads to bedrock.
Note: There are more rooms than pictured.
Update #1
Now that i have a safe, organized place to work its time to work towards acquiring enough supplies to reach the The End and defeat the Ender Dragon!
Favorite this project to keep up to date on my progress.
Update #2
you can now watch me stream at Livestream
(not streaming until further notice due to my comp not being able to handle it and minecraft at the same time very well)

Update #4
I am getting closer to making an attempt at The Ender Dragon or at least entering the end. Feel free to download and look around. Of note is the slime farm with currently two spawn levels, reached via the minecart track, and the blaze spawner trap, which is currently still being worked on, but still yields about 380+ mobs per/hour its kind of a long hike and I plan to add a minecart track to reach it faster very soon. (Added in update 6)

Update #6
Still alive!!! I now have at least 48 hours played and still alive. Finally killed my first ghast today The blaze trap and slime farm are working out nicely, providing drops and lots of XP. I enchanted a lvl 48 diamond pickaxe and was disappointed to receive another Efficiency III :(
Heres an updated world save.

Update #7
small update, I've started construction on a very large farming complex, it will be all automated when complete. Also added a pic.
