The Holt

The Equestrian Holt is a location somewhere within the realm of Urdak that contains a forest and where the Luminarium is held. It has been corrupted by the demons ever since the Icon of Sin was awakened, allowing them to enter Urdak at will.

Overview
Not much known about the the Holt, but with the demons in control of Urdak the Holt has become flooded with their presence, corrupting the Makyr angels along the way. The Holt possesses features similar to Urdak but instead of having a dark teal upper atmosphere it has royal blue.

The first section of the location appears to be a forest with Maykr structures in tight quarters with trees in certain areas and having multiple platforms to proceed further within the forest. There are also floating objects with Maykr like tentacles that repeatedly ascend upwards before disappering and appearing at the bottom before beginning to ascend again. One of the areas contain electric pillars that can be activiated to form a way up to the next area. The forests possess structures that are similar to those found in the Ingmar Sanctum.

Outside the forest appears to be the Maykr stronghold itself, distanced from the forest where the Luminarium is held within the place's holy chamber.

History
During the Doom Slayer's journey to end Hell's invasion, he took the Dark lord's life sphere to The Holt in order to give him a physical body to destroy him. Upon reaching the corrupted Urdak, the Doom Slayer fights his way through the forest to get to the Luminarium where anyone who has a Life Sphere may activate it. while procceding through the forest, VEGA who now is The Father contacted the slayer along the way, explaining to him the events that happened on Urdak and thinking that he'll help him restore Urdak and resurrect himself to a physical body, unaware of the events that happened in the Blood Swamps and that The Slayer carries the Dark Lord's life sphere. Just beyond the holy chamber, the Slayer is confronted by the Seraphim upon reaching the Luminarium’s entrance. Suffering from The Transfiguration, the Seraphim is transformed into a Demon and after a lengthy battle is ultimately defeated by the Slayer and is teleported away by the Father. Despite being warned that bringing the Dark Lord into physical form is irreversible, the Doom Slayer proceeds to summon him and discovers that the Dark Lord is an alternate version of himself who originated from Hell.
