History WMG / FromFakeDreams

Since most Magi can at best keep up with an Assassin Servant, and the current one is Kiritsugu, no Magi can take on the seven servants from the Fuyuki Grail War. The Ancestors themselves could possibly face them, but even then it wouldn't be in their favor, and with the seven Servants all allied with Shirou either directly or through their masters, and Shirou answering to Barthomelloi therefore giving her command over seven Servants, it would make sense the only thing that could match them would be other Servants. And while Kiritsugu may have destroyed the leylines in Fuyuki in order to prevent any future Holy Grail Wars, LightNovel/FateApocrypha proved that Fuyuki isn't necessary to summon servants, just the Holy Grail. So were someone to try and tap into it, possibly Merem, more servants could be summoned.
* Also supporting this idea is a concept from Fate/Apocrypha. It's noted that in the event all seven Servants somehow allied with each other, despite how improbable it may seem, the Grail can then give out 7 more sets of Command Seals and allow the summoning of 7 more servants to reinitialize the war, which is what happened when Yggdmillennia got their hands on it. While Witch!Caster is dead, Fuyuki has access to 7 servants still thanks to the Ore Scales: Arturia, Cu, EMIYA, Heracles, Princess!Medea, Medusa, and Kiritsugu. So with 7 servants allied together, the Grail can call forth 7 more.

** Confirmed in Chapter 60: Irisviel has been summoned by the Grail as a Caster Servant, mostly with her mind, since the failsafe meant to summon a Ruler like in LightNovel/FateApocrypha wasn't completely implemented in this timeline and it lacked in power to manifest properly as a potent avatar of Angra Mainyuu.

** Chapter 53 confirms that what Merem wants to pull is related to the Einzberns, as they openly laugh about the Einzbern representative getting more and more angry over the ritual being dismissed, and how unique Justizia was. This sets Shirou on edge, he knows Merem and the Rat King are laughing about something else.
** Zelretch in Chapter 52 hints at Merem being sentimental (a word which rings alarm bells in Shirou's head), probably over the Fuyuki Grail War inception. Further, Rin tries to get Merem to talk, but the only hint given is "do you know why I am here, of merely who I am here for?", indicating he is here for a person. He also has a mesmerized expression when Jubstenacht appears, hinting at previous interactions (ostensibly for artifacts or relics), and when Justizia manifests herself through Illya in Chapter 53.

* Guess: Merem is here in some way for Illya or maybe Justizia. The attack on his {{Protectorate}} would likely be enough to get Shirou to be murderous.

* Guess: Sakura has sensed something off, worrying her enough that she went to Shirou about this, but it is explicitely not Angra Mainyu or a Grail-related problem. It is likely that it is related to being a Planet Terminal, and to Merem's business.

* Half-confirmed as of Chapter 60. Witch!Caster's meddling with the Grail seems to have manifested [[spoiler:an avatar of the Grail's system / Angra Mainyuu in the shape of Irisviel]]. Illya outright calls said manifestation a Servant.

* One servant possibly being [[Literature/FateStrangeFake Enkidu]]. Gilgamesh giving Shirou his chains will be a ChekhovsGun as the chains will double as the perfect catalyst to summon forth the weapon meant to slay the gods.

Even in its incomplete state, it was rather similar to what it was in canon. Emphasis has been placed on the fact that it is regarded as a memorial for heroes, their weapons littering UBW's landscape. When this version of Unlimited Blade Works is complete, it will go beyond being a landscape full of blades, and allow Shirou to summon a shade of a Hero that owns a particular weapon within his Reality Marble. It's mostly baseless conjecture, but it would make for something interesting, and allow for cameos of other Servants from other Fate works, or perhaps even an appearance from a certain recently deceased King of Heroes.

[[WMG:Shirou hates Archer and wants to kill him for "what he has done" on an instinctual level. What he has done is killing Sakura.]]

* Guess: Shirou, as an Apostle, hates Archer, who is a Heroic Spirit. Shirou doesn't just HATE the guy due to his past actions, he HATES him since he's the counter-thesis of his very being(and he isn't even consciously aware of this). Shirou's current condition being as wonky as it that even Merem, one of the older DAA, isn't sure what he is.
