The Halls of Transcendence
"And as the Hero ascended to Divinity, they took to their eternal place of rest and watch. In marbled stone they sculpted an entrance to the afterlife that would greet the good and bad alike; a place that would guide the mortal souls to their own eternal homes - and keep those of eternity locked out all the same." - The Book of Ascension, The Gospel of Aelfred, 21:5The Halls of Transcendence are the rumored planar home of the deceased that die on Elendor. It was created following The Great Summit to control the flow of souls to to their various after-lives as well as stop extra planar beings from breaching the world of Elendor by force. It often acts as a Limbo with many souls wandering its hallowed galleries for longer than their lives on Elendor and is sometimes referred to as "The House of the Dead".
Travel To, From and Between the PlanesOf course, Mortals and Eternals alike have been able and are able to travel planarly despite the locks on the Gates of Ascension through magical means - however no one living has made it to the Halls. Likewise, magic has been resurrect people from the afterlife to live once more in Elendor. It is theorized theologically that either the magic involved is ratified by the King-That-Never-Was or is too inconsequential for them to notice. Therefore, the gates themselves do not stop the passage of the planes but in fact control the ebb and flow of power between them, which is why smaller interplanar transactions - such as travel, resurrections or summoning's can take place. There is no known magic that can transport someone or something to The Halls of Transcendence. For more info about the Cosmology and Planar travel to and from Elendor See The Cosmology of Elendor.
Purpose / Function
The Halls of Transcendence were formed following the The Great Summit to control the flow and distribution of souls into the various afterlives (And thereby control the power Deities have over and on the plane of Elendor). It is also the divine home of the King-That-Never-Was and his followers who reside in the Gardens of Halcyon at the Apse of the Cathedral.
The Halls of Transcendence are described to be structured like a cathedral in a majority of the Holy Texts surrounding Heroism. According to the Book of Ascension it is a multiroomed structure as well as its own plane of existence.
