The Perrin Sequence is one of the six main Syndicates, led by a former Corpus merchant named Ergo Glast. They aim to resolve conflict with diplomacy and trade rather than violence. As a splinter group of the Corpus, their arsenal consists of modified Corpus tech, as seen in their Secura weapon set. Tenno who ally themselves with this Syndicate 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.
