Zaheer managed to escape his imprisonment two weeks after Harmonic Convergence, using airbending abilities he had acquired due to the planet's energy shift and subsequently liberated his three associates. The latter had been incarcerated for thirteen years following a failed attempt to kidnap Avatar Korra. The only Red Lotus members who were publicly revealed as such were all powerful, influential individuals: the former Chief Unalaq, the truth-seer Aiwei, and a group of terrorists led by Zaheer. The Red Lotus' agenda is to have the humans and spirits coexist again and usher in a new world order by dismantling the established nations and their leaders, which they originally planned to do by releasing Vaatu from his prison within the Tree of Time, and later by assassinating world leaders and ending the Avatar Cycle.
Until 171 AG, the organization operated through sleeper cells, keeping their existence unknown to the world.
The Red Lotus is a global, militant, and self-proclaimed anarchist organization, founded by Xai Bau as a splinter faction of the Order of the White Lotus after the Hundred Year War.
