A collective of brilliant and powerful merchants, splintered from the Corpus. Their goal is to restore order by bringing prosperity and direction to the violent world they study.

Following their own doctrine to achieve Profit, The Perrin Sequence have turned away from the Corpus ideology that conflict must be capitalized upon. Instead these merchants search for ways to exercise their trade without instigating violence.

The Perrin Sequence is one of the six faction syndicates. It is led by former Corpus financier and scientist, Ergo Glast. They aim to resolve conflict with diplomacy and trade rather than violence and despise the Corpus' interest to make profit from it. As a splinter group of the Corpus, their arsenal consists of modified Corpus tech, as seen in their Secura weapon set.

Tenno who pledge to restore order with the Perrin Sequence will receive unique Augment Mods for The Perrin Sequence’s favored weapons after obtaining the title of Senior Executive. The weapons include Acrid, Grinlok, Spectra, and Lanka. The unique effect associated with the weapon mods from this syndicate is Sequence.

After obtaining enough Standing to reach the title of Partner, Tenno can exchange Standing for Augment Mods for The Perrin Sequence’s favored Warframes that include Banshee, Chroma, Gauss, Gyre, Hildryn, Inaros, Ivara, Mag, Nekros, Nidus, Protea, Revenant, Rhino, Trinity, Valkyr, Vauban, and Sevagoth.

The following article/section is conjecture. Content is subjected to change/removal as the game progresses. Please do not use this article for critical in-game information.

The Perrin Sequence is a mathematical number sequence first mentioned in 1876 by French mathematician Édouard Lucas. It is named after François Raoul Perrin, another French mathematician who worked on the sequence in 1899. This is also referenced by the triangular motif of their cosmetics.
According to Cephalon Cordylon, whilst Steel Meridian's and The Perrin Sequence's ideologies do not conflict, their differing methods of resolving conflict does – the former by force and the latter by diplomacy which is the main cause of the negative alignment of both parties, although this may also be attributed from the years of the former's xenophobic culture adapted from the Grineer, a form of hate between the two races which cannot be alleviated with words alone.
One reason that may be attributed to the Arbiters of Hexis opposing The Perrin Sequence might be the views of the Arbiters that see a wide and vast potential in the Tenno, disregarding the Sequence's methods of resolving conflict as reducing the Tenno into becoming mere merchants brokering peace.
Although it may seem odd, New Loka and the Perrin Sequence find themselves working together, most likely because of their shared view of a system-wide peace. The goals of the two are still fundamentally similar, though each of them have their own way of accomplishing it, and their alliance seems to signify a "peace-and-prosperity" relationship.
The name of the Perrin Sequence's leader is Ergo Glast‎‎, as revealed in Update 19.4.2 (2016-12-20). He is portrayed to be a dedicated individual to the Perrin Sequence's cause, ready to sacrifice almost anything to reach "a shared peace". He is the apprentice of Frohd Bek, who would one day redevelop one of Glast's most prized creations, the Animo processor, to be used as the combat AI behind the new Ambulas proxies.
The Perrin Sequence is one of four syndicates currently featured in quests (in this case being The Glast Gambit), the others being New Loka (The Silver Grove), the Red Veil (Chains of Harrow), and Cephalon Suda (Octavia's Anthem).
The Perrin Sequence is also the second syndicate to openly support the Tenno in a regular conflict in the Star Chart, mainly the Ambulas bossfight, the first being Steel Meridian (in Kela De Thaym's bossfight).
Ergo Glast is voiced by Vincent Melamed.
