Chain Riddle (Trial Run)

I'm trying out a new type of riddle. It's a riddle with multiple parts, and each part will lead you to the next one. Not all of the parts will be Destiny related, but the final answer will be. This is just a trial run, so hopefully this goes well. Final answer in the same format as a first letter riddle: 1 ______ 2 ______ ... Final Answer: ______ 1 (Not from Destiny): [i]I am one of many. We were twelve, but now we are fewer, smaller. When you see my light, it will kill you, so I push you all away, though you are just trying to help me achieve my goal.[/i] Guessed by: Blowstuffup10164 Answer: A Halo ring 2 (Not from Destiny): [i]A box without hinges, key, or lid, yet golden treasure inside is hid. [/i] No, it's not an egg. It's from the series that the previous answer is from. Hint: Yes, I am golden inside, but I will not bring you wealth. This gold is for your enemies. Guessed by: Chaddercheese16 Answer: Pulse Grenade 3 (From Destiny): [i]I am a tool of the unused, and you rarely use me. The name of the one who gives me strength has been taken by another.[/i] This is something from Destiny that is similar to the previous answer. Guessed by: The Tree of Ruin Answer: Solar Grenade 4 (From Destiny): [i]I was once sought after by many, but held by few. I am no longer so special. I give strength to the recently discovered in its moment of glory, but I give it to them all, don't I?[/i] The "recently discovered" is the previous answer. Guessed by: CREEP1NGDEATH21 Answer: Heart of the Praxic Fire 5 (Not from Destiny): [i]You must have fallen far to return to me after your escape. No matter. You will perish all the same.[/i] This is from a game related to the previous answer. Hint: [i]This wasn't part of your plan, was it? You fled the last time you saw me, and you are still weak. I will crush you.[/i] Hint 2: [i]STOP STABBING ME IN THE ASS[/i] Hint 3: [i]I WILL SIT ON YOU[/i] Hint 4: [i]Here it began, and here it will end[/i] 6 (From Destiny): [i]I burn those who your enemy's kind hate.[/i] "Your enemy" from the previous answer. [b]Edit 1: These have to be answered in order Edit 2: I'll explain any answers that don't make sense[/b]
