Francois Prelati employs illusions to entrap Gilgamesh, Hippolyta, Alcides, and Tine. Gilgamesh sees right through it (as does Hippolyta). Additionally mimics Enkidu as an illusion to piss off Gilgamesh.
“Alright, that’s enough of that.”
Just as all three Heroic Spirits seemed about to make their moves, the guileless voice of a boy echoed through the snow-covered forest that extended as far as the eye could see.
“...What?”
Tine’s bewildered exclamation came a moment after the boy’s interruption.
“...!?”
“!”
“...”
The queen widened her eyes in shock, the bowman narrowed his eyes slightly, and the King of Heroes ran a suspicious eye over the surrounding scenery.
They should have been standing in a large ravine with only sparse vegetation. And yet, before the boy’s words even had time to register, trees completely filled their view. They were standing in the midst of a forest dominated by the white of the snow that lay thick on conifers, overwhelming the hues of their needles and bark.
Powdered snow fell on Tine’s bare, slender arms, and she felt the chill through her skin.
Forced teleportation?
As she hurriedly gathered a layer of air around herself for protection, Tine attempted to conjecture what had happened to them.
But such advanced magecraft — practically Magic — just isn’t...!
Currently, there was nowhere near Snowfield where it would be possible to see scenery like this. There was the great forest to the west, but the variety of trees was different, and, despite the name “Snowfield,” actual snowfall was rare in the region.
It was also possible that they had been drawn into another world — a unique space called a “Reality Marble” — by a Servant. Tine had heard that there were Heroic Spirits that employed such techniques.
And yet, Tine’s Servant, the King of Heroes, showed no particular sign of alarm.
“Do not lose your head,” he told her. “It is merely an illusion.”
“An illusion...?”
Illusion was a diverse type of general-purpose magecraft. It could be used for concealing a specified place, confusing senses of direction in a specified area, or even cast on oneself to aid in training or reinforce suggestion. Most ordinary illusions, however, were ineffective against targets possessing Magic Circuits above a certain level, or a Magic Crest. As a result, very few mages attempted to master it as anything more than convenient, general-use magecraft. In fact, Tine had experienced having an illusion cast on her in the past, but she was linked to the leylines of the land, and had strengthened her senses through them, so it had had no effect on her.
In the present circumstance, however, she could feel the cold even through the leylines.
...Going by magical energy links, we’re definitely still in a canyon in the land of my ancestors... This really is an illusion, then... But could there really be an illusion powerful enough to fool not just human senses... but the land itself as well!?
How many human mages could have reached that level? With a special medium, such as powerful Mystic Eyes, it would be a different story, but in ordinary circumstances an illusion of that level would be considered beyond the realm of human mages.
...A new Servant!
She could not tell if this was the work of a Noble Phantasm, or of raw magecraft. At the very least, however, it was highly probable that the owner of that boy’s voice was a new Servant.
…
The boy’s voice carried through the entire snowy forest, but it was impossible to pin down where it had come from. It was almost as if each individual snowflake was acting as a speaker for it.
Gilgamesh acted as if he had not heard the voice, and spoke with a tone of mild displeasure:
“To think that there was another mannerless ruffian waiting to spoil my entertainment at the last moment. I do not know what you are after, but did you imagine you could deceive my eyes with this paltry illusion?”
…
“Then how about your ears, Gil?”
Tine turned, and saw a Heroic Spirit. A Heroic Spirit with a face and build that could be taken for either male or female, and to which an indefinable trace of youth clung. A smooth, lean body that reminded Tine of a perfected beast. Features so graceful and beautiful that it did not seem to matter if they were male or female.
This Servant is...
Tine was immediately able to recognize what the entity that had appeared suddenly behind her was. She had only viewed the events from a distance, through a familiar, but this was certainly the Heroic Spirit Gilgamesh had confronted immediately after manifesting; the one he had made the crater in the desert with.
Based on their timing and words, however, Tine also immediately recognized that this must be an illusory fake.
In that case, how would the King of Heroes react? Before Tine could finish turning to look at him, Merodach flashed in his hand and dispersed the illusory Heroic Spirit.
“Who gave you permission to mimic my friend’s form and voice?”
A searing tremor crossed the pass between them to shake Tine’s Magic Circuits. She was able to imagine that the King of Heroes was likely seething with cold rage, rather than abandoning himself to an outburst of emotion.
…
At that point, a crushing noise sounded from a distance away, and tress that were supposed to be products of illusion made very real splintering sounds as they were mowed down.
The illusion was apparently visible to the queen as well. She looked up at the sky, her face a mask of rage, and shouted:
“Don’t mock me! Where are you? Show yourself, dealer in deceptions!”
