#3.7 speculation

I will try to go in chronological order yaya.

So immediately we get the SPDM tower exploding and its immunity broken, and its shown that 'doves' seem to be the source of the immunity: also early prediction the zone immunity was potentially created by the Pax House, who use doves as messengers. This is shown later but SPDM is a pretty big distance from what I assume is Foundation Headquarters, from the looks of the room Ms Stranger, Vertin and Sonetto are in looks similar to Madam Z's room with the big billboard.

Another thing is that we have a Storm happening, either called by Arcana herself or accelerated agains by the Manus to coincide with their attack on SPDM.

The Manus guy we see crush the tower dove isn't the same one Merel fights later in the trailer (see the mask design is very different and their hooded) and we get a closer look as the Manus enter SPDM, but I wanna predict these Manus guys are enhanced by Arcana new form, seemingly much stronger and durable than the regular grunts - gameplay wise maybe they are new variants of the og Manus enemies. The first SPDM teacher we see getting reversed likely was human.

Onto the fight

The location is probably where Vertin and co tried to escape, its so nice to see their locations fully rendered in 3D

the Manus guy is really cool with how the eye switches sockets - the eye also is golden similar to Arcana's

So this bit is more speculation - but notice when the Manus guy partially restores themself note how we see a red stone or thing of sorts return to its head before the golden eye comes back. Now big speculation, what if this is the philospher's stone and these reinforced Manus enemies are actually a byproduct of FMN's work (food for thought)

Cool and awesome fight scene and Vernetto aura farming aside, its nice to see how Sonetto's fighting style is visualised, both her base attacks and ult.

The cameos

the full list is: Druvis, Lopera, Yemolai (Hound), Igor, Lorentz Butterfly, Sliverwing Eagle, Marsha, Naukita, Razor, J, Mr Apple, Regulus, Recoleta before we get the Manus side, and it seems the Manus is likely mounting a full scale attack on the Headquarters

DRUVIS PLEASE HAVE A LARGER ROLE IN THE STORY AND NOT JUST A SHORT CAMEO PLEASE ITS BEEN TWO YEARS

Hoping for a Lopera and Igor confrontation, since the both of them seem to be outside on the frontlines (probably expect some mention and cameo for Ptolmey and Moldir as well)

Still have no idea what to make of the alter Eagle right now

I can't believe Marsha upgrades from riding Death's horse to a literal chimera lets go (I think Senti might appear as a cameo to help out Marsha)

The Manus

the first two are from the 3.2 banquet and play a role in SoS

the next two are from 3.3 (probably a round two of the fight with Igor, maybe 'alongside' lopera

an unknown 'crying' woman - maybe this is 'Nectar' who Copelia mentions.

Final Bit

Da Cube - we know the cube only paritally worked for Igor, and the moment he defected form the Manus it stopped working, and in 3.3 gave it to Vertin. The fact that Igor as a mixed (correct if I'm wrong) arcantist who survived with the Cube maybe means Vertin will use it to save as many of SPDM from the Storm and the Manus

I really don't have anything to say much about Merel's limited form and stuff, maybe we get reversed beyond the 20th century, maybe this form is from the Blank Era, or something else. I really don't know.

Extra rambling

We still don't know whose the white haired person from the stream teaser which is interesting

Note Urd has not shown up once in the entire 3.x

I think SPDM's immunity is probably a lost cause, I don't think the fight in the PV will be successful and the backup dove is destroyed (or if they have a back up- back up dove somewhere)

Alright, the likely playables are Merel and Moth as hinted by the decoded disk from 3.6 and that both of them have been dispatched to SPDM/ the Foundation. I think Ludwig could also be playable since we get three playables usually at the end of patch chapters. Copelia also could be considered as a similar case to Semmelweis back in 1.9.

Some thoughts on the poster and title:

The patch title is On Another's Sorrow in reference to the poem of the same name by William Blake, a poem published as the last song of the 'Songs of Innocence' section where the poem focuses on human love and sympathy. The poem discusses the sympathy of God as well, that while God cannot be always present he can be seen through the compassion of others.

The extent of how much the patch title's reference impacts the story differ from patch to patch (1.7 being overt and deeply tied to the plot while 2.2 the reference is rather loose). The poem being the last one in a section about Innocence can tie to the death of innocence and childhood for SPDM, espeically Vertin. One for the poor kids who are gonna be subject to the Storm and Manus, and two SPDM was the sight of Vertin's loss of childhood in chapter 3. The poem discusses what the speaker believes are the truths about God and how God loves, either the 'God' figure may be Arcana herself. Again had to gauge how much the poem might be relevant.

Storywise:

Why SPDM? - Enigma brings up at the end of 3.6 how Storm Immune zones (Aperion and Antartrica) have strong belief systems or deity worship, SPDM argubly is where the Foundation reinforces its 'Peace for Mankind' dogma the most. At the end of 3.2 Vertin had returned to the Foundation and likely hasn't left for the Eastern Front (I think said Front and the rest of the Zeno/ Igor stuff will carry onto 4.x). The patch series is called 'Roots of the Tale' so likeihood its a full circle moment for Vertin to return to the source of both her trauma and the place she was made the timekeeper.

Concerning the poster summary - I don't know who the little white dove could be refering to, either Sonetto, Merel or Vertin maybe? I say Merel because we know shes been stationed there as reserve forces and that she formally studied at SPDM. There is also the implemation that the immunity of SPDM/ the Foundation is under threat as well. I guess we are due for another Storm.

So here's my theories so far:

Fall of SPDM and maybe the Foundation headquarters

Vertin full circle moment with Chapter 3 parallels (include Sonetto here as well)

Moth, Merel, Creius and Ludwig as potential NPC playables

Outcome of the Storm Protocol Bill - the chance of the Hawks winning

Arcana invading the Foundation

Potentially getting Urd's current whereabouts

Someone being fully restored after being reversed (either one of the Duncan'd, a previous individual coming back or someone new)
