Gameplay needs to be catered toward free to play with a tradeable premium currency. Introducing trade to the game and reworking the way people level up things like weapons and armor and other equipment. Basically the leveling of gear comes from using it a lot, instead of melting down other gear to upgrade its light level. Aside from light level, there's the "motes" depicted as stars on the gear. This affects it even further and could only be leveled by doing repeatable quests involving raids or competitive pvp. gear blueprints can be sold to other players, or you can pack a piece of gear into an engram and put it on the auction house for silver. You can also pack resources like strange coins into engrams and sell them on the market for silver as well. This feature will add a powerful economy that keeps free to play users in the game, grinding for resources and gear to sell to paid users, so that they can afford to buy expansion packs with the silver they earn from other players. Now for the lore of destiny 3. In the midst of a war, the traveler sends out 3 waves of light. The witness looks on and says "I failed yet again. It is happening once more. The first wave comes back to the traveler, ripping the light out of every living being. Zavala looks in the direction of the traveler, and looks around in a daze as if concussed. "why?" is the only word he could muster before the second wave of light rips through the land on its way back to the traveler, causing all living things it touches to wither and decay rapidly. Zavala looks at the flesh melting from his hand and shouts in a strained voice "WHY???" and finally the third wave of light rips through the solar system, returning to the traveler to bring every last strain of life force to its core. The traveler lights up as if satisfied by a good meal, and then rises into the sky and leaves for a new star system, leaving nothing but dust and bones in its wake. No trees, no grass, no water, no flesh. Even the vex remain lifeless without their biological energy stuff. In the lifeless void, osiris steps out of the infinite garden of time and says, "Damn. This happened sooner than I expected. Looks like you've all been waiting here for quite some time. Don't worry, I'm prepared for what I have to do." so he takes a long time but gathers all of the ghosts in a pile.... and i mean all of them... a mountain of ghosts stands before him and he breathes life into them by sacrificing his own light. "Looks like you're all gonna start back at square 1. only this time, without me. I have no more light to build upon. Go return to your guardians, we have work to do." And so the guardians, remnants of the civilization destroyed by the traveler, set out for the stars to find the traveler, you are the newest enemy of the traveler and you seek answers. You're driven to a planet of great beasts, and a race known simply as beast masters. In ancient times, there was a race of parasitic moth people who called this place home. Their parasitic larvae gained traits and genes from the hosts and grew stronger with each generation, and smarter. But that was their folly, as they performed genetic experiments to improve the genetic capabilities of their potential hosts until those hosts grew out of control and became too powerful to contain, eventually taking over the planet with the leadership of telepathic beast masters. The beasts alone or even in groups, are dumb and easy to defeat with a bit of effort in spite of their tremendous strength. but, when combined with a beast master, their AI changes drastically and they become super inteligent dark souls bosses until you kill those beast masters. The second planet, overtaken by fleshy masses. This planet is another experiement gone wrong. The parasitic moth creatures simply realized "why don't we put the powerful genes in a lifeless mass of flesh and parasitize that? What could go wrong" well. the flesh masses gained sentience, and took over the planet like the massive tumors they were. The third planet was a bit more recent. This is where they first discovered frequency technology in the form of resonant crystals that grew from every wall of the underground world. Due to the closeness to the sun, one side of the planet is molten while the other side is frozen. The underground is the safest place to be on this planet, if not for the golems that call it home. These golem were originally workforces of the parasitic moth creatures who gained sentience. They first embedded the resonance crystals into stone, then they etched circuitboards throughout the stone structures that looked more like muscle fibers, for the resonance crystals to pour their energy into the other parts of the golems, the joints of the limbs and stuff were made of hardlight energy attached to these muscle fibers for mobility. You can see single dots of energy moving through the muscle fibers with each movement of the limb they're attached to. much cooler than the vex, but also much more rudimentary, and much more durable. So eventually after powering through these planets trying to restore some semblance of balance, they come across the moth people in their current state, who have already scratched the surface of the light and its effects without the traveler even needing to help and the guardians are like "be careful of the traveler, it's dangerous" and the moths are like "you mean travelers? There's a few life forms in that ball as we can see with the frequency tech and they seem to use a technology we barely scratched the surface of but we know 1 thing for sure, this is not a good technology. this is a technology meant to destroy more than it's meant to build. Thank you for the warning, this confirms our suspicions. The witness shows up and explains the reason for the final shape was to prevent what just happened, and you can convince the witness to become a goodguy known as the redeemed, with the help of the moth people, and raid the traveler's core to find the beings of pure consciousness that call it home. But you run into the same problem the witness ran into... You can't kill disembodied consciousness. so what do you do? Throw it into the void and hope it's gone forever............. which it isn't.
