Archdaemon

Archdaemons are daemon-elementals which are granted the ability to exist on the mortal plane by God. They can manifest in any way, including any mortal animal or plant, or any mineral structure (such as a mountain, or a hill). They are able to communicate in a variety of often mysterious ways, and very rarely they make themselves known to mortals.

Only dwarves have the technology to identify and directly get the attention of an Archdaemon, and it is concealed deep within Dorean Gnosis. This is the root of Dwarven theology, that the daemons are actually living beings which have not revealed themselves to mortals, and must be summoned mechanically. Current methods are very inefficient, and most of the details were forgotten since 1066 BF.

The machine used to summon Archdaemons is the Grand Magnum Ohm
