Bhuster's Craftroom #2 - Minecraft: Nether There (FAILED)

While we're still waiting for the update that Terraria's gonna get soon, I'm gonna be doing this challenge.

Andorr Carpenter was an ordinary guy wandering the world in search for an item he lost. When he stumbled into Antabel, the desert city, he noticed just how eerily quiet it was. No noises at all. Only the sight of dropped items on the ground tell him that people were recently here, but they weren't now. Investigating the piles led him to be ambushed immediately by some of the villagers, who beat him down hard before chaining him up and carrying him to their leader: the priest of the town. He claimed that Andorr was a threat to Antabel's inhabitants, and that he should be banished. His devout followers carried him to the buried Nether portal, where they swiftly cleared the sand out of the way and ignited the frame. Staring at the swirling purple portal, he only had a second or two to yelp before they unceremoniously toss him into it. Lost in Hell, surrounded by danger on all sides, including both above and below him, Andorr must find a way out of the Nether!

Fearing for his last life, something suddenly urged him towards a direction he couldn't find, but in doing so he ended up on fire. On his last legs, a being appeared in front of him, obscured in shadow despite the fire shredding through Andorr's life. The being, though silent, manages to convey an offer of its help. Andorr begs on his knees, terrified of his existence being terminated. And with that, the deed is done, and Andorr appears back in the Overworld. However, as he catches his breath, something in his brain is telling him that he just made the worst mistake that will last the rest of his life. With nothing else to do, he gets up and continues his search...
