Kadingir Sanctum

The Kadingir Sanctum is a level in Doom (2016). It is the first area of Hell which is visited in the game after Olivia Pierce uses an Argent accumulator to rip open a permanent portal to the demons' dimension at the Argent Energy Tower. The Doom marine is pulled into the rift shortly after her, and ends up near the place he was imprisoned by the demons and subsequently found by the UAC. The sixth mission, Into the Fire, takes place here. A barren landscape of craggy rocks and deep caverns is punctuated by portals which require skull keys to be opened.

"The Hell portal is now open back on Mars. Lost in the Hell dimension, you are unable to stop the demons from absorbing our world. Kill everything you see and find a way back to Mars."

Codex Entry
''The Blood Keep, also referred to as Kadingir Sanctum, is a sprawling network of tunnels, catacombs and temples that connect the wasteland Umbral Plains to the Great Steppe. It is believed this area serves as a place of worship and vilification as both hero and enemy can be found buried in tombs across the region.''

''The area is inhabited by all manner of demons, including the Possessed, the Unwilling, Lost Souls, Hell Knights and other non-classified creatures. The Project Lazarus Manned Expedition (MTC 2145/128), uncovered one tomb of particular interest. The temple was adorned with powerful holding runes and unique relics. Despite the complete loss of human life on the expedition, the relics were successfully returned by Scout-Bots to the Lazarus Labs for processing and study.''

Unfortunately, records disappeared after the relics were sent to the Lazarus Labs and they are now presumed lost.

Secret prophecies
Near the third Slayer's Testament rune, a whispering voice can be heard seemingly emanating from a nearby tree. This low, distorted, almost unintelligible voice speaks four different prophecies:
 * "Could he be demon kin, spawned from the loin of a grotesque infidel? Yet, the seal of the heretic binds him. His origin is as dark as his coming."
 * "The power held within the Crucible will punish man-born and demon kin alike. It will crush the divide. It will corrupt all realms. It will create the monster. It must never be found."
 * "Yet even as the Doom Slayer revels in the spoils of his war, another shall rise from the fires: a dark priest consumed by the Crucible. And even the Doom Slayer shall weep in his shadow."
 * "The heretic-turned-apostle Olivia, birthed of the dawn of our resurrection, by her hand we cross the divide. And for her tribute, she shall be granted the form of the Dread Widow."

Trivia

 * The location in or near Kadingir where the Doom Slayer was imprisoned is called the Blood Keep. This location shares its name with from Doom 64.
 * The final arena of this level is additionally designed after the beginning area of, also from Doom 64. Similarities include the Stonehenge-like pillar layout with overlapping crossbars at different vertical levels, and the nature of the battle which takes place there as well - enemies continue to appear in shortly spread-out waves which increase in strength by varying the type of monster, starting with imps and culminating with barons of Hell. Other similarities not confirmed by the map's author include the color of the sky in both areas, and the relative positions of their exits compared to the temple structure.
 * The name Kadingir Sanctum could be a reference to the Sumerian name of the city of Babylon, KÁ.DINGIR.RAKI, meaning "Gate of God."
