Ta'aun, Hand of Oryx

"You will not need these things any more: duty, camaraderie, pride. You will not need an Emperor or a Bond Brother or any other code. You will not need anything at all. You will be your own whole purpose, a beautiful final purpose, everlasting. Cut away these useless things."

- Grimoire description

Ta'aun, Hand of Oryx, formerly known as Primus Ta'aun, was the commander of the Cabal Skyburners. He was taken in front of the Guardian. He was bonded with the Shield Brothers Valus Tlu'urn and Valus Mau'ual. Later he was killed along with Baxx, Hand of Oryx while defending Oryx, the Taken King.

Biography
"You are Ta’aun. Primus of the Skyburners. Veteran of star-shaking campaigns. Bond brother to Tlu’urn and Mau’ual: your beloved comrades. Your faithful friends. For a while you were the mightiest Cabal soldier in the system."

- Grimoire description.

When the Taken first arrived at Phobos, Ta'aun gave the order to evacuate Fleetbase Korus. His intelligence officers filed a report on the ineffectiveness of conventional Cabal forces against the Guardians, and suggested that the technology aboard Oryx's Dreadnaught might be co-opted by the Cabal to nullify Guardian Ghost regeneration. This report was sent up the chain of command to the Emperor himself, Dominus Ghaul, who ordered Ta'aun to personally board and capture the Dreadnaught by any means necessary. After the Awoken armada was destroyed by the Dreadnaught's main weapon in the Battle of Saturn, Ta'aun rammed his warship, Dantalion Exodus VI, into the Hive vessel to land his troops. In the Story mission Enemy of My Enemy, Ta'aun was Taken while attempting to reach the rupture in Mausoleum that led to the realm of Oryx, and was turned into Ta'aun, Hand of Oryx.Ta'aun returns in the mission Regicide alongside Baxx, Hand of Oryx to bar the Guardian's path to Oryx himself.

Despite Ta'aun's strength, the Guardians defeat and kill him, freeing him of the Taken King's control and allowing them to reach Oryx. However, Ta'aun's fate would anger his Bond Brothers, Valus Mau'ual and Valus Tlu'urn, who would attempt to detonate the Dreadnaught's power core to either avenge Ta'aun or force the Hive to surrender. This plan would fail as the Guardians who killed Ta'uan would defeat the Bond Brothers.

Gameplay
Primus Ta'aun is first seen in the story mission Enemy of My Enemy, where he is seen leading his attack force in a battle against the Hive to get to the rupture. He tries to mow down incoming foes with his heavy weapons, but becomes Taken and turns into Ta'aun, Hand of Oryx.

In Last Rites he appears with Baxx to avenge Crota before Eris Morn teleports the Guardian away. He can be damaged but has the durability of a Gorgon.

Returning in Regicide, he fights alongside Baxx to keep the Guardian out of the portal that leads to Oryx's altar. In battle, his Heavy Slug Thrower retains the deadly power and accuracy of those of regular Colossi, and although he cannot fire missile swarms, he can still hammer the player with long range suppressive fire. If Baxx is killed first, Ta'aun will go "berserk" and chase the Guardian until he can either land a hit with his ground smash or is killed himself.

Trivia

 * Ghost and Cayde-6 refer to Primus Ta'aun as a "Centurion" during Enemy of My Enemy, but Ta'aun is clearly a Colossus as he wields a Heavy Slug Thrower, a Cabal weapon used exclusively by Colossi. As Ta'aun, Hand of Oryx in Regicide, his weapon still functions identically to a Heavy Slug Thrower despite its visibly different Hive design. "Centurion" may simply be the catch-all term for a Cabal commander, with Colossi simply being larger, more heavily-armed Centurions.
 * Ta'aun's Taken Heavy Slug Thrower looks like the Dreadnaught weaponized even including the core in the middle. This may be because Ta'aun along with Baxx are the last line of defense before Oryx's throne in the mission Regicide.
 * His gauntlets are very similar in appearance to the Thagomizers exotic.
 * Ta'aun is the only Taken/Cabal to use another enemy's abilities besides Malok.
 * Before being Taken, Ta'aun has the same roar and grunts that a Taken Cabal boss, would have.
 * Ta'aun is the first and only Taken Colossus Guardians encountered so far in the series.
