Nine Gates, Thirteen Seals
The story of 'Nine Gates, Thirteen Seals' is a Dwarven apocalypse tale that spoke of an all-consuming destructive force undoing the fabric of existence. The exact nature of the tale remains uncertain, as much of the prophetic writing is either only partially translated or references vague events. Even the name of the tale is filled with speculation and conjecture, as academics and theologists are unable to agree as to what the gates and seals are referring to. A number of theories have been provided, suggesting anything from Faewild Gates (of which there are dozens, not nine) and Infernal Seals (of which there were only nine, and were destroyed during the Infernal Crisis) to strange machinations out in the fast uncertainty of the Astral Sea, though none are considered "accepted" explanations.
The tale centers around the shards of "a wheel thrice-broken, yet whole in purpose", and warns of the doom that will follow should the shards come to be reunited. It also speaks of "nine holders of Nine lives" and "the Thirteen once combined", believed to be references to the Nine Crafters (the dwarven weavers of fate) and the Many-Faced King (a dwarven mage-king who split his soul across multiple constructs in a bid to prolong his life) respectively. These beliefs are based largely on assumption, as the depiction of the Nine Crafters within this tale is vastly different from their depictions in other dwarven myths, though this is often attributed to the nature of the tale as an apocalypse tale.
Throughout the tale, there are frequent references to the numbers seven, nine, and thirteen, which has been the center of much speculation around the tale. The number three also appears, though only as "thrice", the number itself is never utilized outside this context (or as a part of thirteen). Dwarven myth rarely involves numerological themes, yet the tale repeatedly draws attention to things specifically attached to those numbers. The tale will only mention the count of something if there's exactly seven, nine, or thirteen, or if the number can be demonstrated through a combination of those three numbers. For instance, the number sixteen appears frequently as well, though is always depicted as "seven and nine". The numbers twenty-two ("nine and thirteen") and twenty-one ("thrice seven") also appear multiple times within the tale.
