Operation: Plague Star 2025

Prepare to stave off infection, Tenno. Operation: Plague Star is live until September 24 at 11 a.m. ET!

Following the impact of an Infested meteorite, a pustulating boil now resides within the Plains of Eidolon. You must take it out before it reaches Cetus! While Councilor Vay Hek is in possession of a toxin that can destroy the boil, he has no intention of lending any aid, so you must acquire the toxin before this infestation grows out of control.
