A chronological arrangement of all events and lore pieces currently in Warframe.
This does not include quests themselves as the current star chart progression clashes with established events.
The exact placement of events is rough, but should give a general timeline of things, most importantly, retired events and alerts that are no longer accessible in-game.
I didn't include them in the video because they clash with current progression, but going roughly, here is how the various quests would align in this timeline by going off of a combination of release date, story progression idealism, and current gameplay progression (yes I know it's contradictory). When I inevitably update this video, I'll likely include this list.
Vor's Prize - Listed in the Video
Once Awake - Listed in the Video
Howl of the Kubrow - After Fusion Moa Event, Before Gradivus Dilemma
Stolen Dreams - After the Gradivus Dillemma, Before Hunt for Alad V
The Limbo Theorem - After the Hunt for Alad V
Patient 0 - During the Mutalist Incursions, Before Tubemen of Regor
The Archwing - After Gate Crash, Before Eyes of Blight
A Man of Few Words - After Tubemen of Regor, Before Natah
The New Strange - Before the Second Dream, After Stolen Dreams, (possibly after Second Dream? [Higher MR Req])
Natah - After Tubemen of Regor
The Second Dream - After Natah, Before Operation Shadow Debt
Sands of Inaros - After Operation Shadow Debt
The Jordas Precept - After The Second Dream, After the New Strange
Octavia's Anthem - After The Second Dream, After the New Strange
The Silver Grove - After The Second Dream
Hidden Messages - Before The War Within, After the Second Dream
The War Within - After Operation Rathuum
The Glast Gambit - After The War Within
The Pacifism Defect - After Operation Rathuum, Before Chains of Harrow
Ambulas/Ambulas Reborn - After the Glast Gambit
Chains of Harrow - The actual most recent event on the timeline. After Ambulas Reborn.
Honestly, it's a confusing mess, and a single re-interpretation of a timeline placement could rearrange the whole thing. Here's hoping they fix it someday.
