Built in the Dawn Era, the Hall of Hades is ancient area of Onvorn. The Hall of Hades is place with many ancient crypts. A tributary of the Ebonmurk runs down this honed passage of vaults. On each side of this murky waterway are countless chambers that serve as tombs of those angels and other creatures that fell during the Creation War.
Building on the tombs was started by the angels. As the war progressed, the angels turned the work over to the management of one angel. This overseer and custodian angel was Hades. He built this place with powerful magic and the aid of several dozen earth elementals . These earth elementals were free slaves which opposed their dark brethren serving the primordials. They helped Hades build out the tombs and mausoleums of what became known as the Hall of Hades. This monolithic edifice was built underground so as to better defend it against those primordials that would use necromantic powers to raise them.
The Hall of Hades is truly monolithic, with a uniform river passage flanked by innumerable resting places of the dead. This goes on for twenty miles and then ends at a wall of churning gray clouds. This wall of clouds is the boundary between Bal-Kriav and the Gray Wastes. The river that flows down past the vaults, tombs, and mausoleums is the Ghost River. This is a fitting name, because the area is haunted by apparitions, spirits, restless souls, groaning spirits, and your standard ghosts.
The Gloom Wall may be one-way for most, but the spirits that have crossed over from this realm can sometimes come back from the Gray Wastes. These weak souls still have an attachment to their old lives and refuse to yield to the glory of Hades' domain. It is the duty of us to shepherd the lost to their next home.

The Hall of Hades are defended by a sect of Hades followers called the Caretakers. These priests move freely among the spirits and ghosts that haunt the area. This is a boon from Hades and something gained by any devout worshipper of that god as soon as they set foot in the area. The Caretakers maintain the place, train new priests and send them out into the world to spread the gospel, and defend the area from any who seek to plunder the ancient crypts.
Today, the Halls of Hades, for a fee, is a place where bodies are placed so that they cannot be resurrected, or they can be resurrected at a later time to serve a special purpose. Getting bodies into the place is easy, getting them out for resurrection is not. Generally, the Church of Hades is against resurrection, but if enough of an offering is made, exceptions have been made. Truly remarkable individuals are the hardest to get out of the Hall of Hades, with deals between Higher Powers the most common reason.
