Setem-h'et full title is High Priest of the Temple of Tashent-hat-hor, Overseer of the Priests of Astrology in the House of the Black Ring, Keeper of Set's 4th Mystery, Overseer of the Unnu Priests in the Temple of Sobek, Keeper of Sobek's Second Mystery, and Acolyte Årit Priest in the House of the Black Ring, Sorcerer of the Black Ring.
Setem-h'et, a sorcerer of the Black Ring, is always concerned with purity; he washes daily and has his body hair entirely removed. He is tall and skinny – almost skeletal. He is dusky skinned and has a pronounced hawk-like nose. Setem-h'et must always be in charge; he fears losing control and despises boredom. He is demanding and unfriendly. He is brave and always willing to go into unknown territories and explore new concepts – often because if he is there first he is in charge. He does not work well with others unless the others are taking his orders. However, he is well known and respected throughout the ranks of clergy in Stygia for his ability to get things done and for achieving new results when the old ways fail.
Setem-h'et is usually accompanied by his cohort, Key-nebu, a scribe. Most of Setem-h'et's followers are temple servants and phyle priests spread throughout several temple complexes as spies. He is not travelling with 60 1st level followers. He does travel with a 3rd level soldier follower named Shesmutifi and a pair of 2nd level soldiers named Djeho and Tanenmose.

Teti-sheri's full title is Right Eye of Tashent-hat-hor, High Tcheseru Priestess of the Cult of Tashent-hat-hor, Mistress of the Secrets of Tashent-hat-hor's Tomb, Keeper of Derketo's 4th Mystery, Keeper of Set's 4th Mystery, Third Seducer of Yig in the Temple of Set at Luxur, Judge of Derketo's Acolytes, Judge of Derketo's Umet Priestesses, Overseer of Derketo's Dancers in Luxur, High Priestess of Set's Dancers in Luxur, Chooser of Prostitutes in Derketo's Temple in Luxur, and Acolyte Tcheseru Priestess in Derketo's Temple in Luxur.
Teti-sheri is a charming cultist from Luxur, often described by those who know her as daring and enthusiastic. Her goals usually have to do with gaining the upper hand on those around her so she can influence and/or control them. She never wants to appear in a weak position. Teti-sheri is impatient and somewhat disorganized. In her usual Stygian circles, she generally only wears paint and a string of beads around her waist, but when adventuring or in other lands, she usually chooses to wear a kilt with a belt to hold some weapons. Her bronze dagger, an ornate affair featuring an image of Derketo as the handle with some gemstones, is usually poisoned with either black lotus or purple lotus juice. The bottom of her dagger's scabbard holds a dose of poison so it is poisoned when she draws it.
She joined Tashent-hat-hor's cult to learn the Immortality style of sorcery. She intends to learn some levels of scholar to achieve this. She has been promised this training if she can secure three of Tashent-hat-hor's funerary trappings.
As a Keeper of the Fourth Mystery of Derketo, Teti-sheri can add +4 to any Bluff and Diplomacy checks that she is able to add some component of sexuality to, including seductions, flirtations, or otherwise using her sexuality to get her way. This has not been reflected in the skill statistics included with the character. For those who have Stygia – Serpent of the South, she also has the power of touch as described under the third mystery of Derketo. All other modifiers described in Stygia – Serpent of the South for her knowledge of Derketo's and Set's mysteries have been added to the statistics already.

* feats found in Stygia – Serpent of the South.
An old embalmer from Stygia, Hetepka is a persuasive individual, having risen in rank through the acquisition of important status symbols. An agent of change, Hetepka despises the status quo. He loves to socialise and speak to people, for this is where he is strongest. He is a bit absent-minded, and often inattentive to his surroundings. Although outwardly friendly, he is motivated by prestige and status, something he works to build in Tombalku.
Living now in Tombalku for reasons undisclosed, Hetepka dresses in Aphaki fashion, but the clothing is made from linen. He keeps his head bald (indeed, he shaves off all his bodily hair) even though he has long since retired from Stygian temple life. He keeps a sorcerous garden in the central courtyard of his Tombalku home and still practices as a healer-surgeon. He controls the mummy of a Stygian queen via her funerary trappings. Her new tomb is located beneath Hetepka's home and can be accessed through a secret panel in the floor of his private sanctuary. He teaches a score of acolytes in the methods of surgery and healing he learned in the Temples of Yinepu and Set, and has created a small cult around his mummified queen.
Hetepka's full Stygian title list prior to his retirement was Hetepka, High Priest of the Temple of Yinepu at Khemi, High Priest of the Temple of Yinepu at Luxur, High Priest of Healing in the Temple of Set at Khemi, Overseer of the Priests of Healing in the Temple of Set at Amanopet, Adept Priest of Healing in the Temple of Yinepu at Karnath, Keeper of the Fourth Mystery of Yinepu, Keeper of the Third Mystery of Set, Keeper of the Second Mystery of Seshet, Keeper of the Third Mystery of Djehuty, Guardian of the Seal of Yinepu'em-h'et, Guardian of the Fourth Seal of Hetepka-tifi, Grower of the Garden of Ka'aper, Adept Priest of Agriculture in the Temple of Set at Amanopet.
