Direct answer: The mission "Beyond" in Destiny 2 is the final story mission of the Shadowkeep campaign and takes place on the Moon inside the Pyramid beneath the Scarlet Keep (you launch from Sorrow’s Harbor to enter the Pyramid).

Quick details

  • Where to start: Accept and progress the Shadowkeep campaign until you reach the quest step that unlocks "Beyond" (often listed around the campaign’s final steps).
  • Location in-game: The mission loads you into the Moon’s Pyramid area (Enduring Abyss / interior of the Pyramid beneath the Scarlet Keep).
  • Recommended prep: Many guides and playthroughs advise equipping the Dreambane armor set and bringing strong weapons for the three Nightmare boss encounters (Dominus, the Fanatic, and Son of Oryx).
  • What you do: Explore the Pyramid, defeat multiple Nightmare bosses and complete the mission objectives to inspect the artifact at the end.

Walkthrough hints (bullet points)

  • Make sure you have advanced far enough in Shadowkeep (campaign step ~16 or later) to trigger the mission.
  • Equip Dreambane armor if you have it; some players find the mission much easier with the full set.
  • Expect multiple boss fights and moments where platforming and clearing waves matters—bring area-damage and sustain options.
  • If you get stuck or the mission doesn’t appear, relogging or restarting the campaign step often resolves progression bugs reported by players.

Example resource (video guide)

  • Many players use a full mission video or walkthrough to follow the path and boss tactics; one such gameplay video covers the entire "Beyond" mission for Shadowkeep.

If you want, I can:

  1. Provide a short step-by-step text walkthrough for each boss in the mission.
  2. Link a recommended video walkthrough or a specific written guide for strategies and loadouts.
