The intervention handed by the god of Industry, Reudh, is useful and practical. Reudh most often manifests, when he chooses to- however rarely- is the form of a humanoid flame, with bright wings. To look directly at Reudh is considered foolish- the divine light given off by Reudh is far too bright to be viewed safely by most mogun.
When a Mogun goes 'Fey', they have witnessed this humanoid flame with glowing bright wings in their mind, and it has inspired them. This divine gift creates a craft like none other... however not all mogun can stand to view Reudh in their mind and hence go insane.
To pray to Reudh involves the sacrifice of hand-made crafts- any crafts so long as they were produced by mogun living together are considered holy. Be they made from stone, or metal, or wood- it does not matter, so long as they are properly offered to his temple.
The help that Reudh gives is usually not seen, however it most often takes the form of slight increases in creativity and hence the quality of output- this is most often seen in those mogun who become legendary workers. They often bear the Mark of Reudh on their left hand - a small image of a hammer striking an anvil, or a chisel striking stone.
The followers of Reudh need no more than consider an idea and feel a presence touch their mind, bestowing the visited with the ability to create objects much better than they would normally.
Reudh's wrathful side can be invoked when those who would be known as Building Destroyers live up to their name, or when mogun who cannot control themselves and throw crafts or destroy buildings.
The Wrath of Reudh takes the form of a solid obsidian column consuming the offender, and is often instant death to those so consumed- they simply seem to disappear and are replaced by the cooled black glass.
((For building destroyers, i guess use a random number generator to determine if Reudh will intervene, ie. he has a 50% chance of consuming a building destroyer who comes alone and destroys a building, or 15% for multiple building destroyers sieging together - like if six goblins have six mounts who are all BDs, who all destroy a building/road etc. each, there is a 5% chance to consume the offender for the first building, 15% for the second, 25% for the third, and so on up until 50%.
If an insane mogun destroys a building, he or she shall be considered by his profession.
If said mogun has had a productive life producing crafts and has obeyed Reudh, then Reudh may take pity and only consume them 10% of the time. If they are of a profession that is not crafting, then Reudh will consume them 75% of the time.
Finally, if Reudh's Temple is destroyed by an insane mogun, then the offending mogun shall be consumed by the column of obsidian, and one drop of the Earth's Blood to be dropped near him. This is obviously to be avoided.))
This black glass, this obsidian may be mined out and used to make a new craft, redeeming the offender if they were a mogun and allowing a memorial slab to be used. If the obsidian is not mined out, the memorial shall not be allowed.
((Hopefully this isn't too restrictive.))
