I am hopeful the next expansion will feature The Deep and the mysterious enemy type associated with it in the next expansion. For those who remember the opening scene in Destiny 2, the shadow that ended The Golden Age is a pyramid. Uncanny looking pyramids are awoken at the end of The Red War. A very similar looking one is corrupting hive in the moon. Remember the last scene of Shadowkeep? Look at the sky. It’s coming soon, the tension can be felt. It is only a matter of time before we face the foe that ended The Golden Age again. Dear God, I hope we are ready. If you want to full theory about The Darkness, give me a comment. Also, if you want to contribute more the theory’s surrounding The Deep, please share! For more info on “The Deep” or “The Darkness” see this link: https://destiny.fandom.com/wiki/The_Darkness
