The Summoning Pits
From Destinypedia, the Destiny wiki
In the Rise of Iron expansion, the Strike was revamped, now named The Abomination Heist.
The team of Guardians land outside the Hellmouth.
The Guardians traverse through the entrance to the Hellmouth, and into the Gatehouse.
After fighting their way through battling Hive and Fallen, they come upon a sanctum with a locked door.
One of the Guardians sends their Ghost to crack the multiple locks.
Several doors open, and Hive Thrall come pouring out.
The Guardians fight off more Thrall and a few Knights.
Hive Acolytes and Wizards appear, and the Guardians eliminate them.
The Guardians defend against Cursed Thrall, Knights and Wizards, including Mormu, the Xol Spawn. They are all eliminated as the Ghost finishes its work.
The Guardians travel further downwards, into the Circle of Bones.
A deafening roar shakes the entire cave, shaking loose some rocks and stalactites. The Guardians press on, eventually finding the Summoning Pits. Another roar rumbles throughout the cave system, and a door opens, revealing Phogoth, the Untamed. It stands in the middle of a large arena-sized room, four chains holding it down in the center as it screams in anger.
Moments later, the abomination breaks loose of its chains and attacks the Guardians. They eventually defeat him.
There is a variant of this strike that is only available for the exotic weapon bounty A Light in the Dark. To complete the bounty, the players must defeat a wizard named Xyor, the Unwed, who only appears on the last wave of reinforcements if Phogoth is still alive.
After the release of Rise of Iron, Phogoth was replaced by the Hive Abomination
