Amaryn is the leader of the New Loka Syndicate. She represents them in all their dealings with the Tenno, and also assigns the quest The Silver Grove.
As the leader of New Loka, Amaryn represents the Syndicate in its dealings with the Tenno. New Loka is described thusly:
Only through restoration of a pure humanity and the repopulation of Earth can the conflict end. New Loka are worshippers of the human form and Earth, before its corruption.
No matter how far we reach into the stars, New Loka knows that it is Earth that has always been our home. Turning away from the genetic tampering that has twisted the Grineer and the technological meddling that has corrupted Earth, it is New Loka that fights for the repopulation of a world once abandoned.
New Loka sells the Sancti line of weapons: the Sancti Tigris, Sancti Castanas, and Sancti Magistar. They also carry weapon augments for the Vulkar, Furis, Skana, and Panthera, and warframe augments for Equinox, Hydroid, Mag, Nyx, Oberon, Titania, Trinity, Valkyr, Wukong, and Zephyr. The Syndicate ranks, from least to most favoured, are Exiled, Condemned, Neutral, Humane, Bountiful, Benevolent, Pure, and Flawless. The names of their sigils, in ascending order of importance, are Sacrifice, Seed, Rebirth, Growth, Clarity, Bloom, Purity, Gaia, Bounty, and Humanity.
Greeting the Tenno
(if the Tenno is Neutral rank) "New Loka believes that true humanity is the only path to cleanse ourselves of this suffering."
(if the Tenno is Benevolent rank or higher) "Your humanity is a beacon for all."
(if the Tenno is Condemned rank) "It's not too late to cleanse yourself."
(if the Tenno is Exiled rank) "You're just like the rest. Tainted and ruined beyond salvation."
[Pledge to honour and purify Earth with New Loka.]
"Welcome to our family."
"Give what you can, Tenno, to help us."
(after a successful sacrifice) "You are pure, my Tenno."
"Use these to cleanse the unclean."
"We offer these to aid you, Tenno."
"These offerings are pure."
Purchasing an item
"By the Mother."
"Of course, my Tenno."
"This we give to you."
Beginning Syndicate mission
"Will you help us, Tenno, and our cause?"
When sending death squad
"The impure, the unworthy have no future."
"You will be cleansed."
Amaryn also has additional dialogue in the Silver Grove quest, where she is named for the first time, as well as in Operation: Rathuum, where she asks the Tenno to turn over the Grineer defectors to New Loka for judgement and cleansing. New Loka is mentioned by Cephalon Cordylon in his 5th and 23rd blog posts, and they can be mentioned on a randomised clue during a Nightwave: Glassmaker crime scene. New Loka members can be hired by the Tenno to crew their Railjack.
