Siren Song

"Disrupt a Hive Ritual to keep the Rig from sinking"

- In game description

Siren Song is an Adventure taking place on Titan. It is unlocked after completing Utopia at the same time as the adventure Deathless, and is effectively a prelude to the strike Savathûn's Song

Gravitational Waves are being produced by Hive magic and are destabilising the Arcology. To counteract this the player tracks the waves back to their source in a Hive Summoning Ritual, possibly for the "deceased" Ubara, Hive Prince, which they subsequently interrupt.

Gameplay

 * The Rig


 * Start Adventure

Sloane: Guardian, we're reading some odd fluctuations in our scans.

Amanda Holliday: Gravity waves. Small for now, but amp 'em up and they'll rip us apart.

Sloane: I've got three locations where the waves are strongest. Sending you coordinates.


 * Investigate gravity waves
 * Sites checked
 * [0-3] of 3

 * The player scans the Hive materials at the first site which promptly start roaring like a Knight before disappearing.

Ghost: I don't see anything, Sloane. But I - did you hear that?

Sloane: What are you picking up?

Ghost: It's gone. Maybe I'm imagining things. We'll check your other coordinates.

Holliday: Do it quick. I don't like what I'm seeing.


 * The player approaches the next location


 * Scan Gravity Waves


 * 2 of 3


 * The site screams at the player angrily then vanishes once more.

Holliday: Not to rush ya, but these waves are growin' fast.

Sloane: Get over there, and we should be able to track those gravity waves back to their source.


 * The player approaches the third site of weird Hive gunk


 * Scan Gravity Wave


 * 3 of 3


 * The player scans the final site, which also screams at them like an angry Hive Knight, then disappears back into the Hive netherworld.

Ghost: Sloane, you have to hear this.

Sloane: Oh, I hear it. Amanda's grabbed your data and is mapping the source now.

Holliday: Sources. Three of 'em. Go shut 'em down.


 * Search for the sources
 * Find the sources of the gravity waves

Ghost: Sloane, it's a ritual, a big one. They really ARE going to shake this Arcology to pieces

Sloane: Then let's do the same to them.


 * Destroy Hive Shrine

Ghost: We tear this altar down, we stop that horrible noise.

Sloane: The sooner the better. We're hearing that sound on all sensors now. Feeling it, too.

Sloane: I feel... sick.

Holliday: Keep it together, girl.


 * Find the source
 * Search for the primary source of the waves


 * The player continues through the passage, which is now open since the Shrine's destruction. They enter into a large room, with a gigantic Hive Crystal in the center of it, screaming rhythmically, as per the Hive norm.

Sloane: I'm sure I'm going to hear all about what Amanda will use that for. What were the Hive doing with it?

Trivia

 * This adventure chronologically precedes Savathûn's Song and follows on from the first mission on Titan in which the Hive Prince Ubara is slain by the Guardian, with all three events likely being interrelated.
 * There are few named princes among the Hive, and consequently each Prince is of high rank, with other examples being Crota, the son of Oryx; Alak-Hul, the adoptive son of Oryx and Malok, Pride of Oryx, a son of Savathun, both of whom tried but failed to become a prince after Oryx's death; as well as the Swarm Princes and their lord and master Sardon, Fist of Crota. Given the significance of his rank, if Ubara survived his death by having an Ascendant Realm, then it would have been possible to summon him back in exactly the same manner as Crota was to be returned to life during the Wakening in Destiny 1.
 * If this were the case it would explain the elaborated string of summoning rituals defeated during Siren Song as the crystal at the end of the adventure may be alike to the crystal which contained Crota's soul and was being used to return him to life, and have been prepared in order to resurrect Prince Ubara, though this is prevented by the player's actions to interrupt the rituals, destroy the shrines, and the steal the crystal. With the crystral stolen, if Ubara is in the Ascendant Realm and that was indeed his soul crystal, then he may be trapped there indefinitely.
 * If Prince Ubara was a son of Savathun then her reaction, both emotional and pragmatic due to the Ubara's death and the severance of her son's tithe, would be similar to Oryx's upon the death of Crota, and she would be forced to respond, even personally. This may be the motive for Savathun's attempted summoning in Savathûn's Song.
 * As a reward for completing the adventure, the player receives Songbreaker Grips, Gauntlet's or Gloves depending on their class, identifying what happened to the crystal after Holliday got a hold of it:
 * "They're powered by that Hive rock you got me! Sloane gave me permission once I explained the voltmeter readings." —Amanda Holliday


 * The Hive Crystal is situated underneath a structure identical to the one that housed the CPU taken by the player earlier during the mission Utopia. Whether this is a significant detail regarding the summoning ritual is unknown, and it more likely is simply an indicator of the room's former purpose.
