Ogdru hem

The Ogdru Hem, also known as the Great Old Ones, are a group of unique, malignant alien races of unimaginable power. They are the chaotic, extraterrestrial creations of the Ogdru Jahad which serve as the living embodiments of the unknown and uncharted factors of the universe sent to disrupt the stability of God's creation.
==History==
While there are many accounts of their conception, one legend states that they were formed out of the many threads of the primordial chaos that predated the universe. It is said that before the imprisonment of Azathoth, it released slivers of itself that became known as the Ogdru Jahad whom then later conceived and formed their far more numerous Ogdru Hem offspring.
These beings were created to spread throughout the uncharted dark corners of the cosmos, slowly poisoning it with their influence and corruption. However, it was not long before God took wind of their existence and tasked His archangels with finding and eradicating them, thus, the archangels left Heaven for a time and traveled to the darkest depths of space. The archangels were mostly successful, but were unable to fully prevail in their mission. Many of the Old Ones were unable to be destroyed, and thus the archangels resorted to imprisoning them in either different dimensional planes of existence, other planets, or uninhabited places in space. The remaining Ogdru Hem were able to escape their wrath by hiding.
During the epoch of the Earth's time, several Old Ones found the planet and decided to claim it as their own, however, each time they would be thwarted by their own kind as they were not too keen on sharing. This sparked many wars between the Ogdru Hem which are revealed to be the cataclysmic events that wiped the dinosaurs from extinction. As of now, the Ogdru Hem are either inactive via slumbering in the darkest corners of the Earth or space, or active by telepathically commanding the humans that follow them. The other reason they are in hiding is because the archangels are actively hunting them.
Ever since their arrival on Earth, not only have the Old Ones been in conflict with one another, but were also warring with the Earthly deities that resided upon the planet. The war eventually ended with the deities imprisoning or slaying the remaining Ogdru Hem so as they would no longer pose a threat to the planet and poison its inhabitants. However, despite their destruction and imprisonment at the hands of the gods and angels, their spirits remained intact and hid between the borders of the physical and metaphysical, influencing the mortals that are particularly susceptible to their power into aiding them in restoring their physical bodies so as to reclaim the Earth once more.
==Description==
Unlike their parents, the Ogdru Jahad, the Ogdru Hem are not all necessarily malevolent; even though many among them have the power to end the world on a whim, most never actively seek the destruction of humankind. This is perhaps due to the vast and bizarre power these alien creatures wield; to an Ogdru Hem, humanity just is not worth the trouble of extermination, but that by no means forbids them from toying around with mortals as a child would an insect. The morality of the Old Ones is said to be based around entirely alien concepts and values, once again defining their embodiment of the cold and uncaring nature of the universe.
Due to their advanced age, the Ogdru Hem are often older and vastly more powerful than the average demon, monster, and even angel or deity. And it is said that should they be released upon creation again, they will plunge the universe into darkness and death, a feat that makes them so much of a threat that it forces the angels, demons, and monsters to form uneasy alliances against them. This was proven during the Earth's primordial ages where the angels and the gods worked together to exterminate these malignant creatures from the face of existence.
===Appearance===
As creations of the Ogdru Jahad, the appeaence of the various Ogdru Hem species is designed to make mockery of God's creation, with these abominable creatures often appearing as a twisted fusion of animal features, internal organs, and invasive fungi among other bizarre things of the universe. Odru Hem have often been described as a mixture of aquatic and insectoid features, with only a rare few possessing a vaguely humanoid appearance.
==Eldritch Gods==
Over time, some of the Ogdru Hem have begun to integrate themselves with the pantheons and hierarchies of other beings, accidentally creating beings such as Dagon, a Philistine fertility deity and Hastur, a Duke of Hell, fooling all the demons. Regardless, the Old Ones can contact humans through dreams and there are secret cults throughout the Earth. In the 1920's the Bureau for Paranormal Research and Defense was established to combat the Ogdru Hem alongside their cults.
