Tartaros (Six)

"Reputation is the cornerstone of power and ours has been ruined by the hands of humans parading themselves as fairies. These fairies came to our doorstep uninvited, destroyed our home, our operation and shamed us. Operation: Face was a absolute failure but it has served as rough draft to the prologue of a new story we shall write. A story whose chapters consist of redemption, retribution and regaining our reputation. May the fairies make peace with whatever enemies they have because once the netherrealm has been repaired, there will be Hell to pay."

- Sayla to other Tartarus members

Tartarus (冥府の門, タルタロス, Tarutarosu) was one of the three major Dark Guilds and a member of the Balam Alliance, alongside Oración Seis and Grimoire Heart. Following its crushing defeat at the hands of Fairy Tail in X791 the Balam Alliance has fully collasped leaving Tarturus in ruins

History
Despite there not being any factual knowledge of the Guild, such as their base of operations or the count of their members, it is said by few witnesses that they are a group that gathers to worship Demons. According to Warrod Sequen, they may have had one of the Books of Zeref in their possession.

Post X792
Following its humilating defeat after the guild war between Fairy tail. The once proud and powerful Tartarus was a remnant of its shadow. Its reputation ruined and trodded over by humans parading around under the banner of fairies. Their strength lower dramatically with the fatalities they received. Losing over half of the their original members and their base of operations. The survivors of the affair have been all but humilated and left with the pieces to pick up, however their humilation has rekindled their determination to right the wrongs that happened to them. One day soon the underworld will rise again and there will be hell to pay.

Location and Building
The Tartarus guild convenes in a large building located in what appears to be a barren wasteland. Standing among the rocky landscape, the building takes the form of a giant, slight ruined, castle. The structure itself is very big in size, containing at least three separate sections all atop one another. The two main bodies of the castle are noticeably squarer in shape and decorated with numerous crenulations, whilst the turrets and roof of the castle are more curved, their balustrade lined with decorative machicolations and their spires topped with fancy ornaments. At the gate to the castle stand two large statues. Surrounding the Tartarus headquarters and protruding from the rock are a number of spines, these appearing quite large in size. Whether they are part of the natural landscape or were put there is unknown. This castle was located on a floating island, shaped like, as well as named, Cube.

Operation: Face
The goal of Tartarus was to use a weapon called Face to wipe out all magic from the continent. The reason for their intent to take away Magic from the continent is so that they can gather Curse power in order to revive their Master E.N.D. They would then with their Master return to their creator Zeref. Though most of them are unaware, they wanted to return to Zeref in order to kill him. With the destruction of the guild and the magic weapon Face being destroyed by the dragons operation face was a complete failure
 * Outcome:-Failed

Operation: Netherrealm Revival
Having been forced to rebuild form Ground Zero after the destruction of the cube Tartarus is ina state of massive reconstruction. Due to the laundry list of repairs needed to be done the guild members left over have broken them down into phases.

Their first goal is to gain some new blood to replace the fallen members regaining the strength it has lost. This recruitment process will consist of searching out other etherious or simply recruiting those who have qualities that fit netherrealm's needs, whether by choice or force. This process will be handled by Sayla personally who has taken over as the interim Guild leader following the loss of Mard Geer and inability to revive Master E.N.D. This new blood will not only give tartarus more hands on deck for repairs, but also focus rebuilding a stronger, smarter and more focused Nine Demon Gates.
 * Phase 1

After phase one has successfully been achieved phase two focuses on rebuilding the cube and bringing Hell's Core back online. This in itself is perhaps the hardest and most difficult phase of the plan as raw materials of the previous cube must be gathered in order to rebuild it in the image of the former. Gathering materials will be easy but prove challenging at times as well. With their defeat having been on display their members can be recongnized. To ensure their revival program stays hidden the members will have to work in a clandestine fashion to avoid run's in with other guilds and the magic council. Also more Sin Particles will need to be gathered in order to bring Hell's Core back online and ensure the guild's current members survival in the event of a chaotic situation. With Hell's Core online and the remains of a few of their members it may be possible to revive Kyouka, however the others may be a bit of a stretch. Phase 2 because of it's length and time consumption will without a doubt be the longest phase to conclude.
 * Phase II

Phase III Hasn't truly been disscused much but has been concluded as reparig their reputation, what it details exactly is unknown.
