A week before the Season begins, all players receive a note in their mailbox. It simply reads: "I have returned from the stars. Meet me on Dec. 4 at 10:15 AM PST. —Ada" Once this note has been given out, a small countdown timer appears on the Traveler. When the timer reaches 0, players in the Tower see a ship unlike any they've ever seen land between Zavala and Lord Shaxx. A figure transmats out and walks through the Tower, opening a door that had long been shut. Players follow the character through the Tower and the figure lowers her hood and greets players, "I am Ada, and we have work to do."
The Season Pass in the Director is updated, the rewards are revealed, and now Ada and players begin a Season-long experience of refining forges in the world, completing bounties, finding materials, working on Black Armory armor sets, and taking on the new raid, Scourge of the Past. In a twist, Datto and his group are the first to finish.
As players work together to forge weapons early in the track, smithing and building new ones, the room around Ada begins to change. The schematic data from players' work is resulting in new weapons and mods for players to create. These weapons and mods don't all require playing the Seasonal activity—some of them are found in new encounters within strikes, some of them are forged in Last Wish (like the Alchemy Lab in Blackwing Lair).
As the player community plays, meta objectives are revealed. Once a certain number of players have unlocked ranks on the Pass, cinematics unlock for everyone to watch. We see the Drifter and Ada arguing over something pitting the two against each other, the scene ends with Drifter raising an eyebrow at a set of gun schematics behind Ada.
As the Season winds to a close, the Drifter begins to summon players to him. He's having a new space built in the Tower, and the first people he asks for help are those who've earned the title of Dredgen. Now players begin to gather materials and donate them to fund the Drifter's new scam. The Drifter won't stop talking about the gun schematics he saw behind Ada.
Very late in the Season, players notice Ada's room looks like it's being packed up. She's leaving. The schematics that sat behind her are missing. Over the course of a few weeks, she packs her equipment and, in an event similar to her arrival, she vanishes. Ada, her wares, and her forges are gone.
Banshee-44 reminds players that even though Ada is gone, she left him the schematics for her weapons and armor, and he'll be rotating them through over time.
And the Drifter asks you to visit him, saying he's got a surprise…
