Moonstars are one of the most recent and most covert secret societies to appear in Faerыn in decades. Born in the tumult of a fall-out between several senior Harpers, the members of the Moonstars now operate independently of the former group, though they share many of the same goals. Led by the iconoclastic Chosen of Mystra, former Master Harper, ex-Lord of Waterdeep, and incredibly powerful and knowledgeable mage, Khelben "Blackstaff" Arunsun and his consort, the Mage Lady of Waterdeep, Laeral Silverhand, the Moonstars have spent the last few years establishing their own intelligence network, including agents, spies, informants, adventurers, and a system of portals to allow them fast access to any part of Faerыn.

History
In 1370 DR[when?], Senior Harpers Bran Skorlsun, Obslin Minstrelwish (the Seneschal of Twilight Hall in Berdusk), and Belhaur Thantarth (Master of Twilight Hall) uncovered evidence implicating Master Harper Khelben Arunsun of making deals with the Harpers' archenemy, the Zhentarim. Khelben admitted that he did indeed make the deals he was accused of, and he promptly resigned his position in the group, as did his wife and fellow Chosen, Laeral Silverhand.
These events caused many repercussions. The three Senior Harpers listed above became worried about other "traitors" in the ranks of the group, and they begin investigating many "suspicious" Harpers and their activities; some of their critics use the term "witch-hunt" to describe the trio's tactics. As a result of this internal investigation, some Harpers have quit the group, either to join Khelben's Moonstars or to disappear from the life of an agent completely.
After his resignation, Khelben gathered his closest allies about him and founded the Moonstars, known as the Tel'Teukiira in Elven. One sagely member of the group has located one reference to this Elven term in Amagal's Tome, an ancient elven text of early Cormanthor[attribution needed]. In that usage, the term Tel'Teukiira refers to those who "will come hidden and in many guises and faces. They dwell in shadow and speak in omens, yet they shall bring about waking dreams and save us from the Three Threats Who Wait in Darkness, the Prefects, and ourselves." No one within the group claims to know what this means, although many suspect Khelben knows and is being typically closed-mouthed about it[attribution needed].
In the years since the "Harper Schism"[when?], most of the individuals aware of the circumstances have fallen into one of three schools of thought:
They trust the Twilight Hall trio and believe that Khelben has indeed betrayed them.
Some trust Khelben by past reputation or personal knowledge and accept that he is up to something long-term that will be made clear in time.
Some have ignored the schism and wish only to continue doing good work in Faerыn, ignoring in whose name they supposedly perform their deeds.
Modus operandi
Khelben's first rule for any Moonstars agent is this: Don't get caught while performing Moonstars-related activities. He cares not how an agent spends her days or nights, just as long as she doesn't compromise the carefully constructed secrecy that remains to this day the Moonstars' greatest weapon. All Moonstars agents are prompted to accomplish their missions, but not to risk certain capture. Aborting a mission due to that possibility is never frowned upon. Overt actions that would require such decisions remain relatively rare for the small group at this point, however.
The majority of Moonstars "missions" are nothing more than reconnaissance of targets chosen by the Blackstaff or Laeral. Agents stealthily observe their targets and report their findings, nothing more. At times, however, action is called for and the Moonstars do not hesitate on such occasions. If the Moonstars discover a doppelganger, fiend, or other creature using magical abilities to infiltrate civilized society, the Moonstars act to kill or drive off the monster. Other Moonstars activities that some might view as questionable include the following:
Kidnapping evil individuals for interrogation and a magical "mindwipe" to remove all memories of the questioning;
Stealing (or planting) of magic items and even relics and artifacts;
The “reapportioning” of profits and goods gained by the Moonstars after breaking up or destroying criminal or evil activities.
These are just some examples, and all such efforts are likely known only by the most senior Moonstars.

The Moonstars, also known as The Tel Teukiira, are an offshoot of the Harpers. They were formed when Khelben "Blackstaff" Arunsun realized that he didn't have as much power over the Harpers as he once did. He discovered in the Year of the Laughing Swan (816 DR) that Alaundo the Seer had written prophecies about an as yet undiscovered threat to Faerun. He attempted to steer the Harpers in a direction where they could deal with the threat but, failing that he took matters into his own hands. In the Year of the Prince (1357 DR),
Khelben stole the Scepter of the Sorcerer Kings from the Catacombs of Ordulin, making sure that it came into the posession of High Priest of Bane & leader of the Zhentarim, Fzoul Chembryl. Fzoul then used the scepter to destroy the Banelich Faram Khaldan. 13 years later in the Year of the Tankard, the Harpers found out about Khelben's actions. He admitted his guilt during his trial at Twilight Hall and left the Harpers. Immediately, he and his wife Laeral Silverhand Arunsun set up the Tel Teukiira as part of a plan that Khelben had been developing for many years.
Based in Waterdeep, the Moonstars follow much the same methods as the Harpers do, though the Moonstars operate in more secrecy than the Harpers do and also, members are less free to do what they want, being under the direct and relatively strict command of the "Blackstaff" himself. Officially, the group's headquarters is Blackstaff Tower, though very few have even visited that prestigious place. Each member carries a badge that allows them access to their real stronghold, Silver Safehold which is an extra-planar stronghold built by Cormyrean Sword Heralds.
Membership is less restrictive than the Harpers. One of the senior members is most definitely evil and the organization even lists a vampire amongst its number. To gain entry into the group you do need the sponsorship of either the "Blackstaff" or his wife however, so it is obvious that they do not consider these less morally-inclined members a threat. Many Harpers defected when Khelben created the Moonstars, including Malchor Harpell & Myrmeen Lhal.
Of the gods who pledge their support to the Harpers, only three also support the Moonstars: Mystra, Oghma and Sehanine Moonbow, but even with the lack of the other Harper gods' blessings Khelben and Laeral make up for it with their own spells.
The groups relationship with the Harpers is an ambivalent one. Khelben still advocates the goals of the Harpers to be ones to strive for in his own organization and the two groups goals are nearly interchangeable, yet Khelben also thinks them too narrow-minded and has encouraged others to think that they are simply full of bluster, without actually doing enough in terms of action. The Harpers likewise believe Khelben and the defectors to be traitors to the cause (especially those from Twilight Hall) and sometimes appeal for spies to investigate the "Blackstaff's" plans but hold too much respect for them for anything serious to come of it. They have, however barred Khelben and Laeral from entering the Harper's bases in Waterdeep.
