Tree of Probabilities

Tree of Probabilities is the fifth story mission of the Curse of Osiris campaign and a Strike in Destiny 2 set in the Infinite Forest on Mercury. A fireteam of Guardians were sent back into the Infinite Forest by Osiris to eliminate a Cabal invasion force being simulated within. The fireteam was successful, irreversibly corrupting the simulation through the destruction of the simulated Cabal force and primarily the death of its leader, Valus Thuun.

All dialogue is spoken through the Ghost's comms. {Gameplay}

The guardian fireteam transmats to The Lighthouse, opposite the entrance to the Infinite Forest.


 * Ghost: Incoming transmission. Text only. "Forest created copies of Cabal invasion. Eliminate them."- Osiris


 * Ikora: We still can't track you in there, Guardian. No matter how much Asher wishes we could. If you're going in, watch your back.

The fireteam enters the Forest.


 * Ghost: The geometric data I'm reading from this architecture- it's subtly shifting. Like reality trying to decide on a version it likes.


 * Sagira: In the Forest, time itself is in flux.


 * Ghost: I don't like it.


 * Ikora: Osiris says he's the protector of the Forest, but as far as the Vanguard is concerned, this is your territory. Good hunting.


 * Ghost: Looks like the Vex are trying to reestablish control of the Forest.


 * Osiris: They can try. This Forest is mine now.


 * Sagira: The Vanguard would disagree.


 * Osiris: I didn't ask them.

''The Guardians exit the Forest and enter the Simulant Present.


 * Ghost: While you were fighting, I was thinking of a way over that ramp, so i simulated your sparrow. It's good to go!


 * Sagira: I had the same idea. You just said it first.


 * Ghost: These Cabal must have a leader.


 * Sagira: You're headed straight for him. He's caught in a window in time, trying to steal the map before we can get it. He'll fail every time, but he doesn't know that.


 * Ghost: Sounds horrible.


 * Sagira: A future where he succeeds is much worse.

''The fireteam stops for the first phase of the bossfight. Khartion, Archival Mind spawns in.


 * Ghost: So, where's this Valus?


 * Sagira: Wait for it...

''Valus Thuun jumps in and crushes Khartion. The first phase of the battle begins.''


 * Ghost: The Vex activated their security grid.


 * Sagira: They see you and the Cabal as invaders. Relax, it worked out fine the first time.

Thuun escapes and the Guardian follows him.


 * Ghost: They've activated more lasers.


 * Sagira: It's hard not to admire the artistry.


 * Ghost: It's really not.

Thuun escapes for the last time and is defeated.


 * Ghost: The Valus is down. I can't shake the sense of deja vu. I feel like we've done this before.


 * Sagira: You were here in spirit. I was using your shell.
