"In my position as head of security for Demogorgon, there are few things I have encountered more vexing than the rumors of an Obyrith Lord far to the North in the Screaming Jungle in a desolate wasteland. Try as I might I have never found it, but every so many centuries we catch something both undead and Fiend coming from the North. It has obviously been through great trials to reach us, and it is usually an agent we have sent to the vicinity to investigate. I have sent small armies to see only their leader return as some sort of abomination. I will send no more armies to be stolen from me. If you wish to investigate, be my guest. I will burn your corpse when it comes walking back."


Currently known only to Obox-Ob, Pale Night, and perhaps a handful of whatever ancient Obyrith Lords have survived over the centuries, the Ptera-Gloth's origin is unknown (or at least the few who know it aren't talking). It's purpose seems to be expanding it's domain, which makes it seem hellbent on an eventual collision course with either They Who Lie in Wait (assuming they aren't allies) or Demogorgon himself, especially since the Ptera-Gloth has been forcibly converting the occasional force sent to confirm it's existence.

The Ptera-Gloth appears as an immense rotting Pteranodon with black hide and fires illuminating from it's eyes, open mouth, and belly. It's lower legs and jaw appear to have fallen off, and it's belly is open with rubbery black tentacles hanging from it.


Venom: The Ptera-Gloth's tongue barbs are envenomed. Injury, Fortitude Save DC 38, Initial damage 1d4 Constitution, Secondary Damage is death. Victims who die as a result of this venom rise again in 1d6 hours with the Corpse Creature Template from the Book of Vile Darkness. This even affects Outsiders.

Spell-Like Abilities (Sp): At will: Astral Projection, Awaken Undead, Chaos Hammer, Cloak of Chaos, Desecrate, Detect Good, Detect Law, Evil Glare, Greater Dispel Magic, Greater Teleport, Planeshift, Shapechange, Telekinesis, Unhallow, Word of Chaos.

3/day: Energy Drain, Symbol of Death, Symbol of Insanity,

1/day: Plague of Undead, Vile Death

Caster Level is 22.
Form of Madness (Su): Any creature within 120' of Ptera-Gloth must make a DC 33 Willpower Save (Save DC is Charisma based), or become terrified of the sky. This is a mind-affecting ability that does not affect Chaotic Evil Outsiders. A successful Save means the opponent is immune to the Ptera-Gloth's Form of Madness for 24 hours. If the Save is failed, the opponent will become Panicked so long as it is under the open sky, and will not recover it's senses until it can hide in either a building or some sort of cave or shelter such as thick jungle or forest. It will not willingly venture out under the open sky for 24 hours, and Panics again if forced to do so.

Engulf (Su): The Ptera-Gloth can make Grapple Checks without provoking an attack of Opportunity if it's opponent is at least 1 Size Class smaller than itself. If successful it engulfs it's opponent, and the effect largely depends on what that opponent is. If the opponent is a Fiend it gains the Corpse Creature Template, and gains the Weakness that it must obey every command given it by the Ptera-Gloth. If the opponent is a corporeal Undead, it gains the Half Fiend Template (despite this normally not being possible), and also becomes under the Ptera-Gloth's control. Living beings that aren't Outsiders must make a DC 38 (Save DC is Constitution Based) Willpower Save or die as they are burnt to ashes in the Ptera-Gloth's internal fires.

Immunities: The Ptera-Gloth is immune to Mind-Affecting Effects, Cold and Fire Damage.

Deathly Pallor (Ex): Ptera-Gloth is rare amongst the Obyrith as he has passed beyonf death and returned, a feat that is most odd for an Outsider whose kind cannot normally be resurrected. Ptera-Gloth has all the abilities and immunities of the Undead Type, but none of it's weaknesses (i.e. he is not mindless or subject to Turn Undead or abilities that specifically affect only Undead). It is somewhere between being an Obyrith and an Undead.

Flight (Ex): The Ptera-Gloth's ability to fly is not related to it's wings, and it may fly regardless of the amount of damage done to it. If a way is figured out to somehow render it helpless or paralyzed (or some other condition such as unconsciousness Undead are normally immune to) then it floats to the ground as if under the effect of a Feather Fall spell.

Combat: The Ptera-Gloth will usually use a Spell-Like ability or two to soften up prey before Engulfing them one at a time to add to it's army. Tougher opponents who can fight back, or beings too powerful or too big to use the Engulf attack on receive it's Tongue Lash instead.
