These are the player ran Imps, which are of yugoloth blood stock: ( daemons, not true demon although some times classified as such ) Since they are used as pawns or mercenaries by both sides of the blood wars they should be able to speak both Infernal and Abyssal.
Yugoloth present a great deal of merit in ones true name. Only knowing a yugoloth's true name is the only way of controlling one fully.
They can be bound temporarily, by other means and do tasks. Some of these are agreed tasks others, are forceful ones. ( mainly the wizard may be very close to the true name of the imp, and rather upset the balance, the imp chooses to do the task and let the 'master' think they truly control him or her ( yes her, there can be female implings, the tokens support that hehe )
[[ If you wish to Roleplay as one of these Implings, please contact Me, and I will discuss the rules, If you are involved heavily in other guilds you may not be accepted for this, to prevent human nature from allowing the wrong information to be presented to your potential 'boss" ]]

And help you understand the back-ground of the Implings:
__________________________________________________________________________________
Yugoloths also often called daemons or nicknamed loths.) are neutral evil demonic natives of the Blood Rift who are neutral to the affairs of the other fiendish races, interfering only when they see a situation that may be profitable or a potential for the advancement of their own schemes. The yugoloths are manipulative, secretive, and mercenary by nature, often acting as soldiers for deities in their own private wars, or even at times aiding both sides of the Blood War.

The yugoloths present themselves as simply greedy mercenaries, willing to sell their services to both sides, while behind that public face, the members of their highest castes view the entire course of the conflict as their own thing to control and manipulate until they decide to end it, unify the Fiendish Planes, and turn their attention to the planes of Good.

Like the tanar'ri and baatezu, the yugoloths have their rulers: the baernoloths, who are their progenitors. Below the baernoloths is the ruler of Khin-Oin, who is given the title of Oinoloth.

Yugoloths craving more power sometimes make a pact with the night hags who transform them into unique and powerful creatures, the altraloths. Non-transformed yugoloths find this to be a treachery against the perfection of their kind, but must bow nonetheless before the might of these fiends. The most prominent is the former Oinoloth Anthraxus. Another major altraloth is Charon, the boatman of the River Styx, who ferries souls down the river for a steep price.

# Impling: Implings are more of the messenger spy type of creature, Dark creatures with cat-like appearances, goat legs and feathery black and red wings. These are shape and size shifters, using their powers when and where it is needed for the tasks at hand. Implings are the least of yugoloth, yet in a sense, they some times can be the greatest as they have free will, and the desire to stay unbound. Knowledge of the "Book of Names" keeps these Imps on their toes, to keep their own true names secret. These Imps adopt human names, and often appear a children, to spy. The Implings that are truly free, reside in a secret pocket dimension, they call Rys, which in infernal means "Home". Implings do not seek advancement to other forms, like many of the other yugoloth daemons do. They are happy as themselves, and happy to plot and plan for their own means, using whatever mage cleric demon devil or deity that wishes to summon them for services, to their own advantages. Rys cannot be scryed into, as it has many secret wards to keep these free imps from true discovery. The only way into Rys is via an Imp's own abilities to summon someone to it, or their abilities to escape to it. All free Imps have this ability to go to Rys, only a few have the ability to summon others into Rys. It is hinted that the Secret, Book of Names, called the "Book of Keeping" may be hidden by the Implings.
There are at least four copies of this tome known to exist. However the exact locations of these tomes of power is unknown, and unscryable.
The only type of Wizard capable of using one of these tomes are those that study in depth the arts of conjuration and summoning. Even then they must take special care and consideration when dealing with any yugoloth, as many are very powerful, and very vengeful.
# Mezzoloth: Mezzoloths make up the vast bulk of yugoloth armies and represent the baseline of their race's hierarchy. Mezzoloths form directly from the raw essence of the Gray Waste and Gehenna, either naturally or artificially drawn up from the plane by the engines and spawned pools beneath the Wasting Tower of Khin-Oin, the Tower Arcane, and eventually from the Reflective Chasm in Carceri's Tower of Incarnate Pain. These bipedal, beetle-like fiends wield huge tritons, stand seven feet tall and have four insect-like arms.
# Dergholoth: Promoted Mezzoloths may attain this status.
# Piscoloth: Above dergholoths, these lobster-like yugoloths are cruel, hateful bullies who "keep order in the armies, a task well suited to their petty and tyrannical demeanor."
# Hydroloth: Hydroloths inhabit the River Styx.
# Yagnoloth: These petty rulers are given political authority by the ultroloths.
# Marraenoloth: The boatmen of the River Styx, promoted yagnoloths are situated upon the cusp of becoming Greater Yugoloths.

The Greater:
# Impling: Though an Impling is a lesser yugoloth, by nature, they have the abilities to achieve mimickery of the greater forms. They never achieve true powers of these greater yugoloth, however they are great tricksters and can appear to 'be' something they truly are not.
# Nycaloth: These arrogant, humungous commanders of the yugoloth armies have green-skin, four muscular arms, a doglike or feline head and a pair of large bat-like wings. A small percent of these have dark feathery wings, and goat like legs.
# Arcanaloth: Similar in appearance to the Nycaloth, these fiends dress in fine robes and resemble individual manifestations of a gestalt of the concept of twisted sorcerery. Some of the greatest wielders of arcane magic in the multiverse, they mass within Gehenna's Tower Arcane under the leadership of Helekanalaith, the "Keeper of the Tower," where they record the progress of the Blood War, craft contracts with mortals and fiends alike, and endlessly study the intricacies of abstract evil.
# Ultroloth: The highest, most pure of the greater yugoloths and the undisputed rulers of the yugoloth race, the ultroloths, look like gray skinned humanoids, with enlarged, glowing eyes flickering with malignant color. Their blank faces are devoid of emotion, and their attitude is one of cold, sterile, distant evil. They constantly backstab and betray one another, and are renowned throughout the multiverse for their unbridled cruelty and malice.

A subgroup of yugoloths are known as battleloths. These creatures take the shapes of various weapons.

* Arrow Battleloth: The weakest of the battleloths; often serve as spies.
* Axe Battleloth: Recklessly brave combatants.
* Crossbow Battleloth: The most sought-after battleloths due to their versatility.
* Pick Battleloth: Vicious, predatory yugoloths that feed on the blood of living creatures.
* Spiked Chain Battleloth: Aggressive hunters that hunt down other battleloths for sport.
* Sword Battleloth: Independent and wily, and hard bargainers, they demand conquests, glory, and loot.

* Baernoloth: Sometimes classified as greater yugoloths baernoloths are actually the primal champions of evil who created the yugoloth and demodand races.
* Canoloth: When a yugoloth angers its superiors, whether through acts of betrayal or desertion, it is punished in a way so terrifying that prospect of such a fate keeps most yugoloths in line. Criminals are transformed into canoloths, the blind war hounds of the yugoloth armies. Forever wracked with pain, the canoloths sense their surroundings by means of a long, thorny tongue. They hate all things and relish the chance to maim and destroy.
* Corruptor of Fate: Stealthy and cunning manipulators of luck, they often become assassins.
* Echinoloth: Rear echelons of the yugoloth armies, these fiends combine features of a starfish and squid into an unlovely whole.[citation needed]
* Gelugon: Also known as ice devils, gelugons are actually yugoloths enslaved to Mephistopheles long ago.
* Guardian daemons: These creatures were created by the yugoloths as lesser servants for their mortal allies, and to serve in their stead when powerful wizards call upon them for favors. They are found in least, lesser, and greater varieties.
* Gacholoth: Ebony-skinned, four-legged infiltrators and saboteurs.[citation needed]
* Rakshasa: Beast-headed humanoids descended from arcanaloths, now dwelling primarily on the Prime Material Plane.
* Raavasta: Fox-headed planar humanoids descended from arcanaloths, now scattered throughout the planes.
* Skeroloth: Skeroloths are formed from demoted mezzoloths, who make up the chaff and fodder for yugoloth armies, acting as spies, thieves, and interlopers. They serve because they must, fawning over the nearest powerful yugoloth and betraying former masters whenever given a glimpse of richer rewards.
* Voor: Tentacled, hulking brutes used as guardians, protectors, bodyguards, and enforcers. Greater versions are known as dreadful lashers.

[edit] Yugoloth lords

* Anthraxus. The former Oinoloth, recently usurped by Mydianchlarus.
* Bubonix. A former arcanaloth, now master of the Tower of Incarnate Pain.
* Charon. The ruler of the marraenoloths, ferryman of the River of Blood.
* Malkizid: Formerly a solar serving the Seldarine, Malkizid is now both an exiled archdevil and a lord of yugoloths.
* Taba. One of the greatest spies and thieves in the Fiendish Planes, Taba can appear as any sort of fiend. She uses her abilities primarily to acquire wealth.
* Typhus. Resembling a hunch-backed mezzoloth, Typhus is a powerful general who commands an army known as the Infernal Front.
* Tyranthraxus: This bodiless spirit of possession and flame is called a daemon in Curse of the Azure Bonds. This was also the 1st edition name for yugoloths.
* Xengahra: An outcast yugoloth who has become a living personification of hopelessness. He superficially resembles a solar.

Information on Gehenna from a D&D source.

Gehenna consists of four planar layers that consists of a pair of huge volcanos floating in space, joined at the bottom to form massive groundbergs, hundreds of thousands of miles tall. Smaller mountain-shaped and -sized chunks of earth also float through Gehenna, occasionally colliding. The first layer, Khalas, is a hot and fiery place, but the volcanos gradually grow colder as one passes through the layers; the third layer, Mungoth, is a cool place, while the fourth, Krangath, is icy and dead.


* Khalas is the location of a number of godly realms, including the kobold deity Gaknulak's realm of Aknuthrak, the wererat god Squerrik's realm of Cheisin, Math Mathonwy's realm of Corriegrave, and Sung Chiang's realm of Teardrop Palace.

* Chamada is the location of a number of godly realms, including the giant deity Memnor's realm of Thraotor. It also contains the realms of dead god Iyachtu Xvim.

* Mungoth is the location of an undead god Velsharoon's realm of Death's Embrace and Loviatar's realm of Ondtland.

* Krangath is the location of the orc god Shargaas' realm of The Night Below. It is also home to Hopelorn, Mellifleur's undeath domain, The Obsidian Citidel.


Gehenna was the home of the dark god Bhaal, lord of murder and death, before he was killed in the Time of Troubles.
