I was unable to complete the journey back from the woodland mansion. I wasn't too keen on spending another two hours traversing the seventeen thousand blocks it took to get there, so I opted for the nether. The nether, of course, is a dangerous place. It was fall damage that took me in the end, as I ran too eagerly through a cave I had found after scrabbling through netherrack fruitlessly with my bare hands for too long, a mere 500 blocks from the exit portal. The fall also claimed Fury of the Dragon. Sorry, dragtom, but I feel a lot worse about that than you do.
Rule of thumb for long distance nether treks: don't.
