Lwaxana was a daughter of the Fifth House of Betazed, the Holder of the Sacred Chalice of Rixx, and Heir to the Holy Rings of Betazed. She had a tendency to remind people of this fact when she felt that she had been slighted or whenever she chose to establish her authority.

(TNG: "Haven", DS9: "The Forsaken")

Lwaxana represented the government of Betazed at the Pacifica Conference in 2365. Shortly before arriving to the conference she exposed two Antedean assassins who were planning to bomb the conference with ultritium explosives.

(TNG: "Manhunt")

In 2366, Lwaxana, along with Reittan Grax, was part of the delegation of the biennial Trade Agreements Conference on Betazed. She was kidnapped by Ferengi DaiMon Tog along with her daughter and William T. Riker. They were eventually rescued by Captain Jean-Luc Picard.

(TNG: "Ménage à Troi")

A marriage to Lieutenant Commander Ian Andrew Troi produced two children: Kestra in 2330 and Deanna in 2336. According to Deanna, Ian worshiped Lwaxana. Ian died in 2343.

(TNG: "Ménage à Troi", "Half a Life", "Dark Page")

Kestra was the oldest of Lwaxana’s children. Tragically, Kestra drowned during a family picnic at Lake El-Nar. The incident left Lwaxana so broken with sorrow, guilt, and regret that she decided to repress all memories of Kestra.

(TNG: "Dark Page";)

Deanna was Lwaxana's second daughter. She was born a few months before Kestra’s death.

(TNG: "Cost of Living")

Lwaxana was very protective of Deanna.

(TNG: "Haven")

Lwaxana first met Captain Jean-Luc Picard aboard the USS Enterprise-D in 2364 when she boarded the ship from planet Haven to meet her daughter, Deanna. Picard would find Lwaxana's presence aboard his ship to be an annoyance.

(TNG: "Haven")

She returned to the Enterprise in 2365 while she was in "the Phase," a period in a Betazoid woman’s life when her sexuality was in a heightened state. Her sights were set on Captain Picard.

(TNG: "Manhunt")

Lwaxana apparently "gave up the hope" for Picard, but the Enterprise still remained one of her favorite sites to visit.

(TNG: "Cost of Living", "Half a Life")

According to Doctor Crusher, the arrival of Lwaxana made Picard shudder.

(TNG: "Remember Me")

In 2367, Lwaxana fell in love with the Kaelon scientist Timicin while he was performing experiments onboard the Enterprise-D. Unfortunately, he was to perform the "Resolution," a ritual suicide which people of his race were expected to perform upon reaching the age of 60.

(TNG: "Half a Life")

In 2368, Lwaxana exchanged personality profiles with Kostolain Minister Campio. Their profiles were very harmonious, but in real life, they couldn’t have been more different.

(TNG: "Cost of Living")

Friendships

Ambassador Troi commonly referred to Worf as "Mr. Woof", to which he always politely corrected her with, "It is Worf, madam." For a very brief time in 2365, when Lwaxana was going through "the Phase," she considered Worf as a mate.

(TNG: "Manhunt", "Ethics", "Parallels", "Ménage à Troi")

Lwaxana befriended Alexander Rozhenko, Worf's son, while visiting in 2368 with the intention of marrying Minister Campio onboard. Lwaxana taught Alexander how to have fun, angering both the boy's father and her husband-to-be. She called Alexander her "little warrior."

(TNG: "Cost of Living")

Attendants

Xelo was Lwaxana's attendant but she apparently had to fire him after his thoughts about her became too erotic.

(TNG: "Haven")

Mr. Homn was Lwaxana’s attendant for several years and he often accompanied her on her journeys.
