The Umedyn, and by lesser extent the Astyrdyn and Curydyn are beings of spiritual nature. The Umedyn are beings that do not reside in the mortal realm, they are akin to what humans call “angels” and “demons”, but it is more complex than these concepts. The Umedyn are sentient entities, at least the major ones, and are broken up into three categories: The “Gods”; The Astyrdyn, or the god’s “servants”; and the Curydyn, or those Umedyn who actively meddle in the affairs of mortals. The Astyrkyn are the children of men and Astyrdyn, and are often known as “angel spawn”; Alternatively, Curykyn are the spawn of men and Curydyn, who actively meddle in the human world, these are often referred to as “devil spawn”. Generally there are more Curykyn in the world than Astyrkyn. It seems, however, that no matter who the Astyrdyn or Curydyn mate with, no matter what the race, they are born to appear to be half-human. This fact has lead some scholars to believe that humans are not creations of the Elvydyn, like previously believed, but are the spawn of the Umedyn directly.
The Astyrdyn, while not being the Gods themselves, are considered servants of the Gods. With their own free will, which is how Astyrkyn are made. While they generally do not directly meddle in the affairs of the mortal realm on their own, they will act on the behalf of their patron God. While these are generally benign, the tasks they have been given always serve the purpose of their patron. It is rare that the Gods do their own bidding by themselves, which is why they usually speak through their emissaries, the Astyrdyn. While all Astyrkyn look part human, the Astyrdyn, and also the Gods, come in many shapes and forms. Their forms and shapes depends on how powerful they are, and how well they can be summoned on the mortal plane. If a God must interfere with the mortal world, they will often work through an avatar, such as the Elcarikyn’s Oracle or the Lytherkyn’s “highest” priest. There are reports, however, that some Astyrdyn are not under the patronage of Gods, but are their own agents.
Unlike the Astyrdyn, the Curydyn actively work in the mortal realm, deliberately affecting the lives of the mortals. This fact is why Curykyn are more numerous in the mortal world than Astyrkyn. This active role in the world are usually for their own direct gains, this is why many refer the Curydyn as demons and devils. This reason is why the Curykyn are considered tainted and evil “demon spawns”. The generalization of their race has made the Curykyn hated and persecuted in some places, and in some cities, mainly the Elven cities. Many of these cities refuse entrance to Curykyn, or even tolerate them in their borders. This has caused many Curykyn to resort to banditry and cult worship of the Curydyn. It is often impossible to tell which Curydyn spawned a Curykyn, the same as Astyrkyn. Some Curydyn take credit for more Curykyn spawn than others, but that claim cannot be confirmed.
It seems there is very little difference between Astyrdyn and Curydyn besides their stances on working in the moral world. Some Umedyn scholars theorize that the more an Umedyn affects the mortal realm, the more of the Cury “taint” they receive. While the Umedyn do not lose power or become lesser with the Cury “taint”, it seems the more they receive, the harder it is for them to affect the Astyr domains, and the more “taint” they receive, the less they can affect the mortal realm on their own without summoning from the mortal realm. This theory is why most scholars believe the God’s reasons for not working directly in the mortal realm, but sending lesser beings to do their bidding, minimizing their “taint”. Some of the more embolden scholars think the Gods are nothing more than just extremely powerful Astyrdyn, which the religious community vehemently denies.
There have been some basis to support such claims, and many scholars cite the Duskoralun for that example. Religious text state the Duskoralun’s God, Lylothyl, defied the other Gods by deliberately interfering in her follower’s lives when she destroyed the island of Lyryalun during the mortal war, and for that the Gods cursed her to become a Curydyn, and her followers were also cursed as a result. Umedyn scholars say that because Lylothyl worked directly in the mortal world in such an extent, destroying the island, that the action tainted her enough to turn her into a Curydyn near immediately, and those who worshiped her were also effected as a result. Most Elvydyn scholars will deny this, saying that the action of turning such a powerful Umedyn into a Curydyn, could only come from a massive act of “divine intervention”. In Elven lore, Lylothyl, the Duskoralun God was cursed when, in an act of defiance against the other Elven Gods’ wishes, she protected her people by destroying the island of Lyryalun, creating the chain of islands that are known today. Umedyn scholars say that act, splitting such a large island, was enough power to turn her into a Curydyn, and the result turned her Elven followers into the Duskoralun of today.
One difference between the Astyrdyn and Curydyn is that while the Astyrdyn can come and contact the mortal realm directly, the Curydyn must be summoned by someone in the mortal realm. All Umedyn can be summoned, but summoning a Curydyn is easier, most likely because most Curydyn want to be summoned into the mortal world. The stronger the Umedyn is, the more one has to exert to summon such Umedyn into the world. The Gods are basically impossible to summon if they do not want to be.It takes a large group of people to summon some of the strongest Curydyn, but some are so strong, like Lylothyl, that they are basically impossible to summon as well. That is why most Curydyn must have a cult of followers.
It seems that an Umedyn cannot die unless it is on their own plane of existence, and when an Umedny travels to another plane, they are weaker. That means any Curydyn or Asyrdyn who are summoned to the mortal realm does not die, but is returned to their realm of existence when killed or released. The same seems to go for mortals who have traveled to the Ume, or spirit world, as well, be it the Astyr, the Astyrdyn realm, or the Cury, the Curydyn realm. Asyrkyn and Curykyn, being born on the mortal world, are not tied to their ancestral plane, but to their birth plane.
It is common knowledge that when a spirit on the mortal plane dies, they become an Umedyn entity. Their Kyr, or essentially “karma”, determines whether they “ascend” to the Astyr, or “fall” into the Cury. Religious leaders will claim that a more secular lifestyle will ensure a Cury fate, while a spiritual, or righteous life, will send you into the Astyr. That is why it is said that obeying the Gods are detrimental, because if one of their followers ascend to the Astyr, surely that God will favor them. It is also said, by some of the Umedyn scholars that when an Umedyn is destroyed on their plane, they are reincarnated into the mortal realm, though most religions will adamantly deny this, and saying such is actually considered heresy. Religious leaders say that as an Astyrdyn, the Gods will let you live in peace for all eternity, until the world is again cleansed of all Curydyn and their followers, then everlasting peace shall reign.
There seems to be some truth to that. It seems that the Umedyn plane is partitioned by how many and how strong of Umedyn there is on either side. Umedyn scholars, however, say that when one side completely rules the Umedyn plane, the cycle of the Universe will start over, and all the entities will be reborn and start over in the new world. It is safe to say that the strongest of both the Astyrdyn and Curydyn do not want this to happen. Scholars suppose this is why the other Gods told Lylothyl not to intervene on her follower’s behalf, shifting the balance into the Curydyn’s favor more than it already is. Umedyn scholars theorize that the Curydyn and Astyrdyn cull their numbers so this balance is not too over shifted, for as long as they are not slain, it seems they cannot die, being immortal. Of course theologians deny the Gods ever died or can be destroyed, but have always lived, and always will.
