Alright, so there has been plenty of speculation/comments with regard to the Khvostov (the first gun you get in the game). Here is the idea I had after some brainstorming. First off, this will be a quest that starts from the moment you get the Khvostov, and ends when you beat Oryx (with the Khvostov equipped). To start with, it will be it's basic auto rifle self, with a quest attached to it requiring you to get x kills on each race of enemy, plus x kills with it in the crucible. Then, after beating Atheon on hard mode with it attached, it will change/evolve (increase in light, change from common to uncommon.) Next, the quest upgrades to where you again need x kills against enemy/ x kills in crucible, and then you defeat Crota on Hard with it. At this time, it again gains new abilities/light, becomes a rare weapon. After again repeating and killing x enemies/ x kills in the crucible, and following you defeating skolas, the queen takes the weapon, and with an item you get from killing skolas, she and her witches rebuild the weapon, giving you a weapon that she feels suits you and all your accomplishments. (at this time, you get to choose what it becomes reforged as (handcannon, scout rifle, pulse rifle, auto rifle.) Finally, after getting x kills of enemies (including now the Taken) and x kills in the crucible, along with beating Oryx (on Normal or Hard, I'd leave that up to destiny to decide), the weapon begins to pulsate with a strange light, or some magical power in it seems to activate (or park of Oryx's sword reacts to it), the weapon begins to glow and change, (hinting at, for those conspiracy theorists out there, that the queen knew of Oryx's comming, and she and her witches added something in the weapon that would awaken when you defeated the taken king, one last gift from the Awoken Queen.) At this time, the weapon becomes exotic, and get the perk that it changes elements as you cycle it. So if you have it out and it is solar, you switch to a different weapon, and switch back, and becomes arc, the void, then solar, etc. What do you guys think?
