The Far Realms is a place that exists past concieveable reality. Every moment that you stand entrenched in it, the more clear it is that you are not meant to be there. It is not to say that you can't step into that vast inkyness. You can. But not even the Titans have been able to return sane. It is said what comes from this great darkness is on behalf of the Demiurge, but this is just simply untrue. Paimon says in his experience that which comes from the wall surrounding the garden is very rarely on behalf of the Demiurge itself, though it is known the Demiurge comes and goes from this place as well.
Creatures that come from the Far Realm are called 'Starspawn' or 'Far Realm Spawn'. They come in small hoardes, but can multiply very quickly, appearing like writhing worms and evolving based on the enviroment to various different states of being. They have a appetite for anything and everything within the garden.
Gifts from the Far Realms
In addition another thing to have been known to come from the Far Realms is a series of natural resources, metals and gemstones in chunks that have been given explicitly to The Conclave on behalf of the Demiurge, and that when touched by the wielded hands of divinity tends to dissolve at a rapid rate. The various materials are listed below alongside their purposes.
-Orichalcum. A goldish metal, flaky to the touch. Orichalcum bears a striking resemblance to the radioactive terrestrial elements Plutonium and Uranium but because it is denser it takes fractionally less mass of it to produce the same amount of energy as a larger piece of Uranium. Orichalcum also burns with 100% efficiency leaving no contaminated waste byproducts, unlike the Terrestrial element Uranium which creates waste that must be discarded in radioactive rods.
-Etherium. A light blue type of crystal, which is worth exuberant ammounts. It functions like a superconductor at room temperature, and when mixed with certain other elements causes an uncontrollable fission process that continues until there is nothing left of a planet except light gases.
-Neutronium. A strange black material that seems to suck light in a inch radius around itself. When touched by Mortal hands it has a warm disposition almost as if it is heated, but when attempted to be wielded by divine hands or magics melts into a black sludge and then dissolves. It is extremely dense, and when 'melted' by divine hands, a inch by inch cube could fill a olympic sized swimming pool. This material has the unique quality that when stabbed into the body of creatures, evaporates/disintegrates their soul, cutting the binds of reincarnation, and leyline connection. This is the material that goes on to be forged into executioner and reaper blades.
