You all know Queen Ileosa, right?

Seneschall Corbastia Lettice

Characterized in this tag.

Lord Valdur Bromathan

(NG male human aristocrat 2/cleric of Sarenrae 2), head of House Bromathan. (Guide to Korvosa, pg. 62)

Lord Valdur Bromathan IV loyally serves the temple of Sarenrae as a minor priest. He breaks the chain of House Bromathan lords serving in the Korvosan Guard, a tradition going back to before his family joined the nobility in 4457. This split with tradition has put him at odds with the rest of the house, many of whom serve in the guard or Sable Company. (Guide to Korvosa, pg. 41)

Valdur Bromathan's bodyguard

Unnamed and uncharacterized 

Lady Eliasia Leroung

(LG female human aristocrat 3), head of House Leroung, headmistress of University of Korvosa. (Guide to Korvosa, pg. 62)

The family's fortunes and powers have fluctuated little since its founding, and, although many of the younger nobles of the family gladly wade into the dirty politics of court life, the lord or lady of House Leroung rarely bothers with such things. Indeed, lovely Lady Eliasia Leroung, current headmistress of the University of Korvosa, is considered an ally by most other noble houses, including those at odds with one another. (Guide to Korvosa, pg. 42)

Lady Brie Endrin

Uncharacterized

Lady Sebastia Jeggare

Guard Chaplain according to this tag, and an Aristocrat 2/Cleric 1. Likely an Abadaran, since she's with the Guard.

Lord Rem Ornelos

Uncharacterized, possibly a wizard and almost certainly grew up around wizards and magic.

Arbiter Zenobia Zenderholm

Aristocrat 2/Cleric 9 (Curse of the Crimson Throne, pg. whatever)

Cold and stern to those who deserve her ire, "Zena" (as her many friends call her) Zenderholm has a justifiably fearsome reputation for inflicting upon criminals some of the harshest (critics say unreasonable) sentences among all the city's arbiters. Criminals with access to wealth expend small fortunes on lawyers who can avoid having Zenobia try their cases. Even the most callous and hardened criminals uaver in fear when they face her, becasue they know they have lost their freedom (if not lives).

Zenobia has a softer side, however, and is not without compassion. She doles out relatively light penalties to those who commit crimes from desperation (such as stealing bread to feed a starving family.) Despite this infrequent sympathy, Zenobia saves her true compassion for victims of crimes, volunteering her time to help ease the suffering of those she can.

In addition to her role as a senior arbiter, Zenobia also serves as a middle-ranking cleric of Abadar. Both of her roles frequently overlap, such that she uses divination magic to help her discern the truth in cases even as she provides priceless legal advice (for free) to help clerics and devout worshipers of the god of cities. When she has time, she volunteers her legal services to the city's orphanages, as well as aiding them in finding suitable parents for their charges. (Guide to Korvosa pg. 39)

Field Marshall Sabina Merrin

You've met Sabina Merrin.

Spellmaster Tavid Bromathan

Lieutenant Spellmaster according to this tag, and an Aristocrat 1/Wizard 1. It seems he's since been promoted - and is now the lowest-circle Spellmaster in the history of the Guard.

Spellmaster Maganrad Hestrigsen

An Academae student convinced to join the Guard by Cressida Kroft.

Maganrad (LN male human enchanter 10):

Maganrad is an Ulfen wizard and a student teacher at the school [...] He's tall, lanky, and kindly looking. [...] If the PCs wish to speak to Maganrad, they find him much more willing to talk than the other NPC three NPC contestants. He came to Korvosa by ship as a young boy from Kalsgard in the Land of the Linnorm Kings, and quickly took to the local language and culture. When he discovered he had magical talens, he made arrangements to fund his entry into the Acadamae, where he has studied for the last 9 years. Although he is certain he could have passed the graduation tests years ago, he is mindful of the 10-year enrollment commitment at the school, and has not pressed the matter. Soon he will qualify to graduate and earn himself a place on the Acadamae's prestigious staff.

He hopes that adding "winner of the Breaching Festival" to his list of accomplishments will help secure this goal. (Academy of Secrets, pg. 8)

Watch Sergeant Cressida Kroft

She knows everyone and I bet that includes you

Watch Sergeant Jope Chantsmo

(LG male human expert 1/ranger 7), owner of Trapper's Hole. (Guide to Korvosa pg. 62)

Trapper's Hole: Owned and operated by retired Sable Company marine Jope Chantsmo, this shop sells all manner of hunting equipment but specializes in archery supplies. Jope sells every kind of bo wand arrow common to the continent, as well as a few exotic pieces from distant Tian Xia and Arcadia. [...] Jope hates crossbows, so he carries none and kicks out anyone who inquires about them. (Guide to Korvosa, pg. 23)

Unnamed and uncharacterized

Archbishop Ornher Reebs

Archbishop Ornher Reebs dedicated the new temple, with the help of the Acadamae's headmaster, in an appropriately infernal way, sealing a pact with an erinyes using the blood of 13 virgin sacrifices. While all of these virgins volunteered for the dedication, some observers speculate that a few were charmed or otherwise magically compelled to join the festivities. 

The conclusion of this dedication sent shockwaves through the city, and Korvosa's citizens threatened to riot, raze the temple, and topple the monarchy. Queen Domina calmed the city by expending her own personal wealth to import a powerful cleric, who then attempted to return all 13 sacrifices to life. Only four of the virgins refused the service, and most of the other nine are still alive today. (Guide to Korvosa, pg. 17)

Vault Colonel Qualins Rachmirol

Here's an alternate future version of Qualins Rachmirol. There's no guarantee, though, that it has anything more in common with today's edition than a lemure has in common with a maledicted paladin.

Vault Captain Portenus Gaskelinni

(LN male human expert 2/fighter 2), owner of Leftover’s. (Guide to Korvosa pg. 62)

Leftover's: East Shore's only inn contains 12 two-person rooms in addition to its large, cozy common room. It charges standard rates and offers standard amenities for an inn. The one-armed innkeeper, retired soldier Portenus Gaskelinni, happily tells the story of how a Shoanti berserker relieved him of his appendage just before he returned the favor and separated the Shoanti from his head. Two Oathday nights a month, Gaskelinni's Korvosan Guard buddies stop in and reenact the skirmish (with blunt, wooden swords) for amused audiences. (Guide to Korvosa pg. 14)

Vault Captain Harmanuel Kendall

Uncharacterized, but someone in his family has an amphitheater named after them. 

Lieutenant Vault Captain Tauk Par

(CG male human barbarian 6), Theandra’s bodyguard. (Guide to Korvosa, pg. 62)

Three Rings Tavern: This quiet tavern belongs to retired adventurer and former Pathfinder Theandra Darklight (originally Theandra Mulnsk). Thandra earned enough coin as an adventurer to buy a decrepit tavern in Five Corners and fix it up. [...] Thandra took to the settled life with great gusto [...] remains a good-natured and friendly person, ready to help a friend in need and always hungering for a tale of hhigh adventure and daring-do. 

A few years ago, Theandra lost a few fingers when a bar brawl turned ugly, which led her to hire the half-Shoanti barbarian Tauk Par as a bouncer. [...] Tauk Par watches over the place like a hawk, eyeing regulars and newcomers alike with the same barely concealed dislike. (Guide to Korvosa, pg. 26)
