We know that throughout the series the Puella Magi can only search for witches and don't actually know where they will appear ahead of time (Mami named places she searched and had to trace the witch with her Soul Gem), unless they get lucky and find a grief seed of a newborn witch (like the one Madoka and Sayaka found at the hospital).

Homura was able to know where Walpurgisnacht would appeared because she had prior knowledge from coming from the future.

However, in the first timeline, Mami knew Walpurgisnacht was coming and was training Madoka in preparation for the battle. Is it explained how she or Madoka knew?

    I assumed all the information came from QB. He'd know of major events in the system. And WN seemed a good way for some forced suffering. I'm not currently sure if there is any explanation in interviews or materials. Commented Nov 8, 2014 at 20:05

As a matter of fact, Kyoko asked Homura the same question regarding Walpurgisnacht's appearance, to which Homura responds with a single word:


Well... I think you can take Akemi Homura's word for it. She has experienced so many timelines, planning and fighting the Walpurgisnacht witch, gradually learning more and more about it every time.

I suppose she's done a lot of data analytics about the witch with all the information she has collected throughout the timelines! Graphs, annotated sketches of the Walpurgisnacht witch and maps of Mitakihara city feature at Homura's residence. Also note that among the timelines shown, all of them place the fight scene of magical girls vs the Walpurgisnacht witch in one of the lakes/water bodies of Mitakihara city.

Here's Homura indicating the location of the witch...

I would suggest that Mami knew about Walpurgis in the first timeline of episode 10 only because Kyubey said so. After all, the Incubators do plant grief seeds across the city, which hatch into witches. In fact, I wouldn't be surprised if the Walpurgisnacht was the work of the Incubators. In all their advanced technology and magic, the Incubators may even fabricate grief seeds which has the essence of an agglomerate of regular witches...

  • But does this explain how Mami and/or Madoka knew about Walpurgisnacht's coming in the first timeline? as per the question "in the first timeline, Mami knew Walpurgisnacht was coming and was training Madoka in preparation for the battle"

  • @Memor-X Oh yeah, I've updated the answer. Remember, If something goes wrong, blame it on kyubey...

There is slight nuance here. Walpurgisnight is a natural phenomenon that happens all the time. Just like places where hurricanes happen occasionally, you are going to encounter one sooner or later if you start living there. Mami knew Walpurgisnight will come sooner or later. She just didn't know when and where. It might have been next week or next year.

Homura on the other hand knew exactly when and where it will come.

    I don't know about that... there's a clear sense in the first timeline of episode 10 that Mami expects a Walpurgisnacht soon, and that there's an urgency to her getting Madoka battle-ready.

    The thing about Walpurgisnacht being a natural phenomenon i think is incorrect, Witches are not naturally occurring and the storm cell which everyone in the town was advised to take shelter from is just the destruction it cases (i think Homura in one episode says this)

The top answer has effectively answered your question about how Walpurgisnacht's appearance is predicted in later timelines. However, its appearance is still known in advance without Homura's intervention.

  • In Madoka Magica episode 10, Mami is actively preparing for Walpurgisnacht's arrival.
  • In Kazumi Magica chapter 22, Kyubey briefly mistakes Kanna's amalgamate witch for Walpurgisnacht, implying that it could suddenly appear in a similar manner.
  • In The Different Story chapter 2, Kyouko tells Mami rumors she's heard about a superdreadnought witch called Walpurgisnacht, which is notable since this long predates Walpurgisnacht's arrival in the anime.
  • In Magia Record, the Magius' plan revolves around luring Walpurgisnacht to Kamihama as the power source needed for the Automatic Purification System to extend around the globe.

Most notably, however, Walpurgisnacht does not drop a grief seed. In the timeline where it is defeated by Madoka and Homura alone, the only grief seed they have access to is Oktavia's.

This can't be attributed to the annihilation of its soul as in Magia Record, as neither Madoka nor Homura have a power capable of such like Ren does. And Portable does confirm it has a Grief Seed.

Walpurgisnacht's Grief Seed

So where does its Grief Seed go, if it has one but never drops it even when seemingly defeated? Well, what if it doesn't die when it's killed? This would readily explain how it's well-known in advance; it's never truly killed, but simply exits reality and waits. It has been defeated before, by magical girls who would warn their younger teammates of the witch that tears open the day, and it would be defeated again if the timeline hadn't consistently been reset after its appearance in the anime.

Further supporting evidence, which is less reliable due to being pulled from unreleased materials:

  • The Rebellion sequel's title, Walpurgis Revolution, implies that the witch is somehow capable of persisting past two true resets, even though logically the Law of Cycles should immediately destroy it once it appears.

  • A witch exclusive to Portable, Itzli, is specifically noted in the lore as only appearing after Walpurgisnacht's defeat. Like the character introduced by Scene/Zero, Aki Mabayu, Itzli has a film-splicing motif, and could thus potentially have powers over editing herself into reality if she is in fact a part of the Walpurgisnacht amalgamate. Supporting this is Mabayu's suspiciously Walpurgisnacht-like appearance:
