Ophissra, Mother of Nightmares

Ophissra (Pronounced Off-iss-rruh) is a primordial serpent often associated with Yuan-ti religion.

Origin
According to legend, many millennia ago an ancient being called Wadjess gave birth to the first serpents of Londorwin. Largest and strongest among them were Ophissra and Asarraj.

Appearance
Ophissra had always been depicted as a colossal snake with midnight-black scales. Her eyes, a bright yellowish green. When she opens her mouth it glows with an eerie purple mist. It is believed that this mist is the essence of countless nightmares she has devoured.

It is said that her voice is like a malignant whisper that can send shivers down your spine and drive the weak willed mad.

Interests
From what is known about her, Ophissra feeds on nightmares. It is her goal to become strong enough to devour the world. Legends say that her venom could induce a coma like state in which the victim would experience an endless array of nightmares.

Nyxes-ra Dynasty
During the time of the Nyxes-ra dynasty, Ophissra was worshiped as their chief goddess.

The Devouring
The Yuan-ti believed in a future event called the the Devouring. On this day Ophissra will have finished feasting upon the denizens of Londorwin's nightmares. At this point she will become powerful enough to devour the world. Over the next year Londorwin will progressively be plunged into an eternal night. Once completely swallowed, the world will fall into chaos for thousands of years.

Nkhetiss (The Resurrection)
After thousands of years spent in darkness, Londorwin will emerge from within Ophissra with only the strongest of it's inhabitants remaining. The world will bask in the light of the sun and experience a time of peace and prosperity.

Shedding
Once Nkhetiss (on-kett-iss) has begun, Ophissra will shed her skin and become Asarraj the sun serpent. She will then take on the responsibility of protecting the reborn world.

Asir-ra Dynasty
During the current dynasty of the Yuan-ti. Ophissra is seen as an evil god.

Nubisath (The Cleansing)
Towards the end of the Nyxes-ra dynasty, it is written that the serpent god Sseth flew down from the sun. He told the Yuan-ti people that Ophissra was misleading them. He informed them that the sun serpent, Asarraj, was not their goddess reborn, but in fact a separate being entirely.

He explained that Ophissra only wished to lure them into false hope, by telling them of Nkhetiss when in fact her true goal was always to consume the world forever.

With Ophissra nowhere to be found, the Yuan-ti had no reason to question what Sseth had told them. Sseth talked of how salvation from Ophissra's wickedness could be had, if only the Yuan-ti renounced their faith in her and placed it with the true Asarraj. The majority of the Yuan-ti believed Sseth and took Asarraj as their new chief god.

With Ophissra painted as an evil god, all those who refused to stop worshiping her were enslaved, imprisoned, or in some circumstances executed. Among those who still believed in Ophissra and Nkhetiss was the Pharaoh Seknuit, her husband, and others of the royal family.

The Pharaoh's son Asirkht killed her husband and captured her. He waited and executed her himself on the steps of the royal palace in the Yuan-ti capital, Emphiss. Asirkht became Pharaoh and the Asir-ra dynasty began.

The Devouring
The Yuan-ti still believed Ophissra would devour the world, but now it is seen as an end time to be avoided. They believed that the only way to do so is to become powerful through conquest and control. If the end times arrived and they were strong enough to defeat Ophissra, then they would prevent the Devouring from occurring and Asarraj will reward them with the prosperity they deserved.

Cult
Amidst the ruins of the Nyxes-ra dynasty, worship of Ophissra survived through a fanatic cult known as the Coil of Nightmares.

They believe that Sseth was jealous of the love Ophissra received from the Yuan-ti and is using the Night serpent's persona of Asarraj, as a cover for his own desires.

They will do whatever is necessary to bring about Nkhetiss as intended and believe that the non-believers will perish when Ophissra swallows the world.
