Blood Knights

The assassin's guild that Lidara Mormaer joined at age ten. Lidara was exiled at age 18 when she brought danger to the guild. The Blood Knights are a part of the Zhentarim network. Most members of the guild are born into it, and begin training at a young age. Lidara is unusual in having been brought in later.

Chaol
Lidara's ex-boyfriend and a shitty dude. He trained together with Lidara when they were young. He was a very caring and encouraging person, and eventually, he becomes Lidara's best friend. Lidara and Chaol loosely started "dating" when Lidara was fifteen, and this relationship continued for the next three years, until Lidara was exiled from the Blood Knights.

The Strings of Fate met Chaol again when they were sent on a mission up north. Chaol was on an opposing mission for the Blood Knights, and when that conflict came to a head, Chaol chose his own mission over Lidara's life, and stabbed her. Later, Chaol tried to get himself back into Lidara's good graces, saying that Lidara was powerful and strong and that he still had feelings for her. Lidara refused, realizing that she would never be able to trust him the same way she once had.

Now that the Blood Knights are under new leadership, it is unknown if Chaol is the leader.

Cymeria
Cymeria is a very happy and bubbly person - the opposite of Lidara. When Lidara first joined the Blood Knights, Cymeria came up to her first and basically forced Lidara into friendship. Lidara went along at first, but they ultimately grew to become really good friends. It was good for Lidara to have another girl friend that she could talk to about things and know that she has her back.

Cymeria was an ally during the siege of Ciniath, and (as far as we know) is still alive and well.

Mikarym
Mikarym is "a lot." He is very fiery and sarcastic, and he and Lidara got into a lot of arguments because he knew how to push her buttons. Eventually, their hatred and annoyance with each other calmed, and they became friends despite the rocky start.

Mikarym was an ally during the siege of Ciniath, and (as far as we know) is still alive and well.

Hydris (deceased)
Hydris found Lidara when she was ten, and took her under his wing as a trainee of the Blood Knights. He taught her the basics, and for a time she considered him a father figure. Later, however, she realized that she was really just a pawn to him, and he did not actually care for her.

While in Ciniath, Hydris attempted to hunt Lidara down. At this point, he was a shell of his former self. Lidara killed Hydris during the final battle with Manshoon, sending him careening into the Astral Sea.
