A shifty, shape-shifting Raavasta who knows Citadel Mercane like the back of his hand. Has been useful in locating some of the seedier elements of the Citadel. Not bad with a dagger either.
Scaramander
Demonic underworld kingpin of Citadel Mercane. Wants TBD to murder Trethrix so that he can become a Diamond. Claims that Trethrix is responsible for allowing Rel'thrik's death
Taikus
Crotchety and grizzled Githzerai black market smuggler. Allows TBD to use his portal to Tu'narath
Gharvag
Second in command of the Separatists. Dispatched Rel'thrik to the Citadel Mercane to meet with TBD, but never heard from him. He is the main Separatist contact for TBD in Tu'narath and gives them the missions to free Vlaakith and overthrow Zetch'r.
Vlaakith CLVIII
Rightful heir to the throne of Gith. By all accounts she is a determined and ruthless leader with no time for Tiamat and her machinations. If freed and she is able to ascend to the throne, Gharvag promises that Vlaakith CLVIII will stop all Githyanki invasions, ally with TBD, and expose Tiamat's breaking of the ancient pact, thus ending the Githyanki's war. She is freed by TBD as the first step to ejecting the Gith from Tiamat's war. After Zetch'r's failure and the destruction of Vraxanault, she ascends to the throne and reunites the Gith.
Vraxanault, the Red Terror
Leader of the red dragons allied with the Gith. He is displeased with Zetch'r's performance and abandons him to TBD. When he sees Zetch'r in trouble, he returns, but leaves again when Goretash destroys the scepter of Ephelemon. He attacks them once again when Theo reantagonizes him. He is killed by TBD after a hard fought battle. Theo suspects that he is Tiamat's red exarch.
Rel'thrik
Githyanki separatist sent to meet with TBD at the Dreaming Spire. Killed by a Blue Dragonspawn in front of the Maruts. Left a message with TBD to go to Tu'narath to make contact with the other separatists
Trethrix
Member of the Society of Seven Diamonds. She rewards TBD for helping to quell a demon attack in the Citadel's bazaar. Accused by Scaramander of being paid by Tiamat's agents to look the other way when they kill Rel'thrik
Rhapsody
Tiefling owner of the Morningstar Inn, the base of the Separatists. She is a Separatist member.
Vlaakith CLVII
Mad queen of the Githyanki. She was a tyrant, fueled by an ever-burning lust for immortality. She was assassinated by the Black Arrow. While most were secretly relieved, she was succeeded by Zetch'r, an emperor who is, arguably, much worse. More perplexingly, he is the first Githyanki leader to not be a prophet of Gith.
Emperor Zetch'r
Puppet emperor of the Githyanki. He was among those who assassinated Vlaakith CLVII and secretly broke the ancient pact with the Red Dragons in order to become emperor. In return, he is but a vessel for Tiamat's machinations.
