The World Machine
In the beginning, there was the World Machine. A device of wondrous complexity, It encompassed the entirety of the Universe, somehow becoming something greater than the sum of Its parts. Self-created, it contained all possibilities within itself. It remains beyond the comprehension of lesser beings, but it may be termed Mostal. Three components were of special interest to dwarf lore: Helper, the first tool; Linchpin, the central support; and the Mostali, independent repair and maintenance units.
    The Mostali were of different kinds. Called the Octagony of Ancient Minerals, the types were: Rock Mostali, who mined and built structures; Lead Mostali, who developed methods to control the dynamics of moving substances; the Quicksilver Mostali, who learned the transformation and combination of liquids and gasses; the Copper Mostali, who developed containers and transport mechanisms; the Tin Mostali, who mastered techniques of automaton construction and essence control; the Brass Mostali, who learned the combination and refining of metals; the Silver Mostali, who mastered the methods of magic and enchantment; and the Gold Mostali, who studied and codified the methods and knowledge of the others.
    Helper, the first tool, created more tools itself. These tools, the Mostali used to maintain and refine Linchpin, which some other races call the Spike. A structure constructed of adamant (which is refined truestone), it was a wonder to behold. The Universe functioned flawlessly, all the parts contained within their orbits, fulfilling their functions.
    At some point, Error was introduced into the World Machine and it began to suffer malfunctions. The precise nature and source of Error is still under some investigation, but it seems clear that these were the result of a number of other forces: Growing, typified by the elves, and Taking, typified by the trolls. The Iron Mostali were developed by the Octagony as a response to these threats to the Machine. They developed the tools and methods of warfare to combat these malfunctioning forces.
    The Mostali were of superior construction, but were heavily outnumbered by malfunctioning units. In response, the Octagony met again and created the so-called Clay Mostali—the dwarves. Although somewhat less magical and intelligent than the Mostali, they were much easier to replace and more numerous, and eager to help with maintenance operations.
    Then, at a critical moment in Error repair operations, the Linchpin was destroyed as Entropy swept through the system. Most of the Mostali were destroyed. The Universe plummeted towards oblivion.
    Emergency repair operations began immediately, spearheaded by the dwarves, the most numerous repair units still in existence. Working slavishly, they attempted to repair the World Machine faster than it was being destroyed. Some despaired at what seemed a hopeless task. But the remaining Mostali and dwarves persevered and many outlying factories and outposts were cheered when the Sun rose, indicating that major repair operations were correcting the Errors in the system. They were inspired to iron discipline, working ever harder to complete the Machine’s repair. They know that the Error is not yet fixed, for the perfect universe has not been restored. Yet.

Orders: This “church” has ten distinct orders, one for each of the castes. The orders do not have virtues distinct from the Way of Mostal, but their magic is geared towards the functions of their caste. No other schools or orders are compatible with the Way of Mostal. The practice of any other form of wizardry immediately brands the dwarf an apostate. Dwarves that stay with the Way of Mostal, even if heretic, never age nor die naturally. However, apostate dwarves are subject to the unnatural force of death. They begin aging at varying rates that seem to be based on the overall physical and mental characteristics of the individual; this is a powerful incentive for dwarves to remain in the fold.
Other Side: The Mostal node is a complex structure with its apex in the Saint Plane that connects to a base of ten nodes in the Spell Plane.
Disadvantages: Every aspect of dwarf society and magical practice is stratified to a level beyond mortal comprehension. Devout dwarves are mostly incompatible with life outside their cities.

Diamonddwarves
Diamonddwarves are not a caste. Rather, they are an attempt to replace the lost True Mostali who were destroyed during the Catastrophe. A dwarf of any caste may attempt to achieve diamonddwarf status; in fact, most do so when they have achieved the minimum necessary qualifications for Examination.
    Player dwarves who wish to turn their character towards diamonddwarf status may only do so with their narrator’s approval. He must have at least nine appropriate abilities at 1W2. Appropriate abilities are those listed in his order keyword or occupational keyword. He must have two Mostali Virtues at 1W2 or greater. Finally, he must have a relationship of 10W with his supporters. The Examination was standardized at the beginning of Time and has a resistance of 10W3 or more.
    The Otherworld will intrude on the hero, who will undergo voluntary and involuntary heroquests. He will also face challenges from ritual enemies during his ascension. This is Error attempting to stop the repair of the World Machine. A successful hero’s final quest brings him to the realization of his diamonddwarf status.
    The character pays 3 hero points to gain the relationship Diamonddwarf of [Stronghold] at the same rating as his current Worship Mostal. The new diamonddwarf  loses all other relationship abilities except for his relationship to his supporters.
