Zelretch was annoyed. He had seen the effects of multiple interactions of the fifth holy grail war and, while he enjoyed the many types of mayhem it could cause, it still grated on him that the fight was ultimately meaningless.

As long as the Grail remained corrupted by Angra Mainyuu the fight would remain pointless, no wish can be made for the Grail and that was a bummer for Zelretch. A huge bother indeed.

"Wait, what if I change things in one of the timelines?" Zelretch said to himself while walking through the halls of the Clock Tower, his comment causing many of the magus to sweat bullets at these words.

They could only hope it had nothing to do with them, and it really didn't have.

Not that it served as much of a consolation for the many magus there, nothing involving Zelretch was ever good for anyone.

Zelretch, with practiced ease, ignored them all. Moving with purpose he went towards a certain section of the Clock Tower that was heavily guarded. Of course, Zelretch being Zelretch just bypassed it all with practiced ease and entered the place by sheer brute force.

If he can slap the moon with one hand then there is little anyone else can do to make him stop when he is moving with purpose. Entering this place, he frowned. He was not exactly happy to be on the Sealing Designated section of the Clock Tower where all items that are considered dangerous or property of the Clock Tower are located.

Looking around he found his targets, it was two pieces of skin with many red markings on it.

The Magic Crest of the Emyia family and another from a family of Magus that went extinct, sort off at least. It was the Senji Family that specialized in enchanting and creation of Mystic Codes.

With a smile he took it, he turned around and could see a fuming in fury Bartomeloi advancing towards him, her face a mask of pure terror to all those minor nobles scurrying off and away from her.

Zelretch could have dealt with her, quite easily in fact, but he had better things to do. Namely, he used the Kaleidoscope to move straight towards the ROOT. If there is one person who knows how to go there, it is Zelretch, and he was experienced in going there too. He went there once when he mastered and took full control over the Second Magic as well as when he went ahead and created a path for one to obtain the Third Magic.

One person can only ever fully master one True Magic, true, but Zelretch had come to a special idea that could be highly interesting a while back and he decided to test it out.

With the two Magic Crests, he moved to the Root he forcefully augmented them. Turned their limited abilities by bringing forth the information of all it's infinite possible understandings of the infinite universes thanks to his Kaleidoscope.

It wasn't enough to truly reach the level of True Magic, but it was a hair's away of it for both of them. Now, armed with the two items he wanted (one he needed, one as just a bonus he thought well deserved for a certain young man who so entertained him), he returned to one of the worlds where the fifth Holy Grail War was about to begin.

Moving silently while dressed like a ninja (it is Zelretch, what else would he wear when going stealthy) Zelretch first went to a certain red-haired aspiring magus.

Entering his room he saw the boy nowhere to be seen. He then moved to the shack on the side and saw him there, laying on the ground sleeping peacefully.

Moving to beside the boy he raised him up and took out both Family Crests, placing them both on him at once.

The boy opened his eyes instantly and was about to scream in pain when Zelretch put a hand on his forehead and forced him back to sleep. He then continued the process, integrating both the Emyia and Senji family crests on the boy. Normally this should take weeks or even months to fully and perfectly integrated, but let it not be said that Zelretch, with knowledge of infinite universes, could not do a better job at it.

In about three hours he was done with the process. The boy now having his original 27 circuits + 46 of the Emyia crest + 37 of the Senji Crest for a grand total of 110 magic circuits of varied quality with those from his circuits being almost comparable in power (after the contact with the ROOT) to those of the Bartomeloi, which is speaking a lot considering they were all of only average quality beforehand.

With the boy on the ready, he moved to one of the places where the Main Grail was located. With practiced ease, Zelretch forced his own energy into the boy's to help in a special operation for the Grail. Using the Emiya Crest, the power that originally only served to control one's own time and now was extremely similar to the power of the Fourth Magic, the Operation of Time, he began turning back time on the grail itself as he cleansed it from the interference of Angra on the summoning.

The process was not easy, but it was working. Pieces of Angra were removed from the Grail and thrown out a bit at a time, disappearing into nothingness.

After a whole day doing just that Zelretch finally completed what he intended to do. He had removed all the stain from the Grail on this timeline. With a smile he began removing his energy from the boy, returning the Grail slowly to the current time while no longer having any of the corruption of Angra in the Holy Grail.

However, he failed to realize a small, really small and tiny problem. The Grail basically supported a God for over 70 years now, but with the removal of all the power and influence of Angra and returned to the current time the magic energy that would have been spent in maintaining him, this excess energy reacted a bit excessively.

Latching on to the power of the Emiya Crest and the Kaleidoscope energy around it from Zelretch, it began activating, not to use any specific action but to deal with the excess energy there. The result was a unique event that Zelretch would in the future swear he did not intend it, but was happier about it that he should have been. As the energy connected with multiple universes at different points in time, the results were extremely chaotic.

Well, to be fair the troubles would not really be in the future though. It is in the opposite direction of the timeline really.

It was in the past now, and things would get very, VERY messy.

AN:

A plot bunny from my head. I do not guaranty I will follow through with this story, be aware.

Anyway, yeah I made Shirou BS strong. Mainly, Shirou is now in possession of TWO of the True Magic, or at least something extremely close to it. He has the Fourth Magic (time manipulation) and the First Magic (Creation from nothing).

As to what is going to happen, imagine the fourth holy grail war, but with three factions (Fate/Zero Faction; Fate/Stay Night with characters from different routes present and the males servants changed for female servants and with Shirou having Ex+ Rank in Harem Protagonist luck; Fate/Apocrypha with a mix of Red and Black Factions) on it instead of only one and every faction fighting for supremacy. As long as there is one surviving faction all masters and servants can get a wish.

I did this because I had a dream, a beautiful dream of seeing how Rin would react seeing her father, knowing what he put Sakura through, and the wonders of what Shirou would do to a certain worm if he were to be this powerful.

And finally, there will be no repeated servants. That means, Shirou will not have Artoria, but he will have, Umu, the next best and look-alike thing.

Oh goods, imagine Artoria, Mordred, and Nero in the same fight over Shirou.

Anyway, Reviews, Favourites, and Followers are appreciated =)
