The history of the hallowed necropolis revealed.
The endless writhing serpent
The Ur-River is thought to be the most ancient of all watercourses in the Mortal Realms, and the most enigmatic. It is believed to have no headwaters and no outlet, instead crashing from one realmsphere to the next, its course constantly shifting as it grinds a new path through the Realms. It can often be followed for leagues, sometimes even across whole continents, but will always drop off the edge of the world eventually. Some of these cascades are stable Realmgates, used for trade, travel, and war. Most are simply destructive torrents, and those who sail over them are never seen again.
When the Mortal Realms were young
Even during the Age of Myth, there were events which had already passed into legend. One among them was the tale that told of how deep in the wylds of Ghyran, Sigmar knelt to wash his face in the Ur-River, and beheld a vision of the gods he would raise into his new pantheon. Perhaps there is truth to this tale, passed by the God-King to his followers, or perhaps all it is is the grand lie of some ancient demagogue. Regardless, the Ur-River’s forbidding Ghyranic shores quickly became a place of sacred pilgrimage. From naught but rock and ice a shelter and then a settlement sprang up, seeing to sojourners’ spiritual and worldly needs.
A time of terrible prosperity
In the centuries which followed, that settlement grew to become a towering edifice: Amasya, City of Worship. It became commonplace for the Pantheon’s most devoted servants- Man, Aelf and Orruk alike- to journey there to die, or at least to consign their remains to oubliettes carved high in the cliff faces. Thus were laid the foundations of Amasya’s transformation into the hallowed necropolis, a place of death in the Realm of Life.
Against the motley of a thousand orders and sects, a need emerged for a single voice to shepherd Amasya’s many flocks. Thus was the office of Basrahip ordained, the last and greatest of which were the Mithridates.
The Age of Myth wanes
Four generations of the house of Mithridates would reign over Amasya. Devout of Alarielle, Mithridates Uch was the first ordained, even as the insidious influence of the Ruinous Powers began to corrupt the Mortal Realms. The Pantheon shuddered and splintered apart in the decades that followed, through the time of his son and into that of Uch’s grandson, Mithridates Besh.
With Amasya largely abandoned by the worshipers of all save Sigmar and Nagash, Besh renounced the Goddess of Life kept by his father and grandfather and converted to servitude of the Undying King.
The crusader capitol
With the Age of Chaos crashing down upon the Mortal Realms, Mithridates Besh reformed Amasya not as a place of peaceful worship but a mustering ground for holy crusades. The practices of Nagashizzar became commonplace, all but replacing Sigmar as the preeminent god of Amasya and turning the worshipers of Sigmar and Nagash against each other- even as the city’s faithful campaigned against the armies of Chaos time and again.
Having been dealt a grievous injury by a daemon, Besh commanded his son Mithridates Alti to bury him living in the cliff-side tombs above Amasya and take up his father’s mantle as Basrahip. Raised in his father’s shadow on the battlefield, Alti did as he was told, his faith in Nagash absolute.
With Alarielle in hiding and Ghyran all but lost to Grandfather Nurgle, the now-ordained Mithridates Alti was soon counseled by his city’s Sigmarite priesthoods to abandon Amasya and withdraw to Azyr before it was too late. Alti raged at the priests, declaring them cowards and refusing their warriors the honor of answering Sigmar’s call to do battle at the Allpoints.
Nagash’s total betrayal of Sigmar at the Allpoints was easily justified in the eyes of Mithridates Alti. As word of the Undying King’s treachery reached Amasya, the Sigmarites made the decision to abandon the hallowed necropolis. Taking with them only their most sacred treasures and collapsing every Realmgate leading to Amasya in their retreat, they fled before their vengeful Basrahip’s return. These actions spared the necropolis discovery by those sworn to the Dark Gods, yet would leave Alti bereft, cleaved from his home and denied burial alongside his forefathers. Then the Age of Chaos swept over the exiled Basrahip, and the name Mithridates Alti was lost to history… for a time.
