Simply talk to Annatar, corrupter of Celebrimbor and forger of (most of) the Rings of Power. So, story is...you're a young elf in Eregion (or are you...?), and you run into Annatar in a dark alleyway. He strikes up a conversation. You can answer as Celebrimbor, Telperinquar, Melkor, Morgoth, or any other name! The other questions are yes or no, but choose wisely! (Also, you can answer the yes or no questions as either 'yes' or 'Yes' and 'no' or 'No'.)
Based on the Akallabeth in the Silmarillion. Thank you to JRR Tolkien for his awesome books. No thanks to Amazon for their butchery which is coming out in fall, I think. Yes, my art is horrifying. No, I'm not apologizing.
