Darlioth, the Eltharin rune used to symbolise the Mirai, the "Black Pit" that is the Elven Underworld.
Mirai, otherwise known as the Black Pit, is the Elven Underworld, and the dominion of the pantheon of dark Elven deities known as the Cytharai.
Ruled by the Elven goddess of the dead, Ereth Khial, the Pale Queen, Mirai is the destination after death for all Elven souls not snatched away by Slaanesh or sheltered within Tree Kin or protective waystones.[1a]
Few Elven souls are seized by the Pale Queen's wraith-like servants known as the Rephallim, who must be quick to steal them away from the Dark Prince of Chaos and his eternal thirst for delectable Elven souls. Yet no paradise awaits these souls, for Ereth Khial offers only eternal torment and servitude for the Elves within her dark kingdom -- all out of spite for the Elven creator god Asuryan who once spurned her advances.[1a]
The Asur believe that there are places on the island-continent of Ulthuan that act as physical entryways into the Black Pit. These Adir Cynath are cursed places, where no living thing save for plants dares to dwell for fear of attracting the Pale Queen's gaze.[3a]
Last Gate[]
Mirai is guarded by Ereth Khial's son, Nethu, who acts as the gatekeeper to the Black Pit and the realm's guardian. Keeping a ring of silver keys for the gate of the Underworld, Nethu ensures the gate remains sealed until the coming of the Rhana Dhandra -- the Elven apocalypse. It is also Nethu's duty to see that no intruder breaches the Mirai to steal away the secrets of the Elven dead -- at least, not without offering a suitable tribute to the Pale Queen.[2a]
A host of Dark Pegasi watch unblinkingly from the battlements of Nethu's dark fortress. Easily mistaken for statuary by the unwary, when roused, none are safe, for their shadowy maws consume soul-stuff as easily as mortal flesh.[2a]
