Mine was in the nether with that crazy wither skeletons. I jumped into the glowing purple wall of.....whatever it is made of. Enchanted diamond sword at hand ready for attack. The Nether loaded and I hoped out on the brownish-red netherack. Near my portal I saw a fortress. Perfect. I went on over, making a bridge of cobblestone over to the fortress. I sneaked so I would not fall into the burning hot lava below, I knew If I did there would be no chance of return , no more of this game because I was playing hardcore. I went into the fortress. All I saw was a maze of walls, not knowing where to go I went right. After a few turns I found a dead end and a chest. I opened it. OMG! DIAMONDS!!!! 2 shimmering diamonds sat in the chest along with a worthless golden chestplate. I took the diamonds. Someone decided to show up when I closed the chest. A wither skeleton who killed me. I am dead. That ended that game of hardcore. I didn't even get to fight the ender dragon.
