'Not a lot of options' isn't the same as no options at all, You tell yourself. Rider certainly didn't give his life just so you could give up, so close to the finishing line.
You're still frozen on the same spot you were, just before one of the side rooms. Your eyes flick towards Lancer, then back to Caster. By the smile on her face, she knows you're evaluating your options. For her part, Caster seems content to give you a moment, perhaps to take in the futility of anything you could do.
You don't risk a glance back into the room, but you remember the sensation of your command seals tingling. That crystal was important.
The War had gone wrong from the very first night, when your Servant had been stolen. The only one to have the expertise for that would've been Caster. The very same Servant whose workshop you stood in now.
"Can we?" You ask, "You're not exactly a civilized Magi."
Beside her, you feel Accolon glaring at you for the proffered insult. Morgan says nothing, but sighs. Before she can say anything else, you continue.
"What did you do with Alice?"
"Alice?" Morgan tilts her head a bit, "Ah, you must mean one of the fledgling Mages. Is that girl why you charged in here like some hero? No wonder. Both she and my former Master are crucial to the survival of this entire city. You know of the Dead Apostle that approaches the city - Einnashe, I believe you call it."
You nod. "The Church has the tools to handle it. Even I could've repelled it if I hadn't been busy fighting this war, fighting
you."
This time she laughed, "Fool. Your Church had but one plan, and that was spoilt weeks ago. They have been desperately-"
A feared sorceress from the twilight of the gods and the noontide of the faeries she might be, but even Morgan le Fay had no way of reading your mind. The first warning she has is the twitch of your fingers and of Lancer's feet, simultaneous. You reach for your pockets, where you're holding the last of the bramble-grenades, and Lancer leaps straight into the room like a bullet, spear aimed squarely for the crystal.
But Morgan le Fay was not famed and feared for nothing. There is no reaction from her, no shock or startling. She responds to your provocation so fast it was like she was going to strike at that exact moment regardless. Her response isn't a weak one either.
Space
extends. Time
slows.
You throw yourself backwards, and it's like you're falling through honey. The air is leaden and sluggish. In front of you, Morgan raises her hand almost lazily, unaffected by the weight of the air. Beside her, Accolon and the remaining Homunculi spring into action, and they're
so much faster. They vanish from your eyes the instant they start moving, their speed easily ten times what it had been earlier.
Morgan le Fay had blasted you and Lancer out of time into a realm many times slower. But your thoughts aren't slower, and neither are the living objects you carry on you that
aren't you.
All four bramble-grenades explode simultaneously. You
scream as barks of iron and thorns shred the front of your face and body, despite your best efforts to direct the explosion. The mass of thorns from floor to ceiling sends you flying backwards, howling in agony but unable to clutch your face as your arms and legs are still entrapped in slowed time.
You aren't blind. Against all odds, you can see. Not one thorn had sliced your eyes out. The world is a sea of blood. Through a haze of red you spend a year blinking rapidly and turning your head to look at Lancer. He has been pushed even deeper into the time-slow than you, and seems almost frozen in midair.
Before him, the ten paces to the crystal were ten-thousand paces now, and with the next blink a hundred thousand. Before your very eyes the room becomes a corridor, and the corridor extends until it reaches infinity, and the crystal vanishes from sight. But not from sense.
Through the infinite corridor the crystal's light reaches you and Lancer. It's the first colour other than red you see. It's blue, and gold, and warm and soft in every way your thorns were not.
You have no words. You can't even raise a hand or clench a fist. Blood floats in the air, a fountain of crimson lazily flying upwards from your body as you fall.
-BREAK IT!!
Searing light erupts from Caster's hands. A silver streak of light that carves a molten trail along the roof and floors, cutting through your brambles with east. From the edges where the light had touched it the remainder of the brambles erupt in flames. Caster sweeps her hand, cutting across horizontally, slagging the walls of her basement. The light passes right before your eyes, missing you by inches, and if your vision hadn't been drenched by the film of blood over your eyes you're sure it would've blinded you before you could even close them. Still you slowly open your mouth into a wordless cry as the heat of the beam burns away the falling blood into vapour and blisters your face.
The spell wasn't magic or light, it was pure fire - so hot that it was white, and so condensed it was a solid beam.
Your command seals pulse for the third time that night. The seals you had gotten from Thomas, Rider's former master, are all gone.
Even an endlessly long room must have an end. An opposite end, or else it simply would not be a room but rather something else. The Command Seal cut through space and time, and bodily took Lancer, hurling him at infinite velocity across the intervening distance. One moment Lancer is only a few feet away from you, the next instant he's teleported right beside the crystal, spear poised to strike.
Before the spear touches the crystal itself it hits a barrier. A corona of pale mauve light shimmers into existence and the spear explodes against it in a shower of sparks.
"What kind of Caster do you take me for, boy?" Morgan smiles, "The kind to leave valuables lying around unprotected?"
No, you
had anticipated the protection. You just had no way of knowing how strong it was. Your only hope had been that Lancer's boost would last long enough for him to smash through.
For the first time, a flicker of worry appears of Morgan's face. A single crack appears on the mauve surface of the shell over the crystal. The worry is there and gone in an instant. She raises her hand again, fingers like claws, and slashes the air. Titanic blades of air shred what little remains of your wall, passing clean by you into the room.
You finally hit the ground. Time isn't slowed anymore. Both Accolon and the Homunculi ignore you, rushing straight for Lancer, moving in right behind the wind blades. The space-warping effect is also gone. Only fractions of a second remain.
The crack in the shield widens, and the very tip of Lancer's spear is inside. As if in response to Lancer's presence, the light inside the crystal becomes more and more agitated, shifting and shuddering in a frenzy. It's like there's a person imprisoned in the crystal who knows release is close at hand. The moment Lancer's spear breaks through, the light… leaves. It's seemingly siphoned off into the spear, streamers of blue, gold and silver light passing out of the crystal and into the servant.
Lancer meets Accolon's blow just before it would land, lance to sword, and
breaks him.
You throw up your arms to cover your face and roll to the side, as a near-hurricane blasts out of the room. The pain from your slit muscles and flapping skin is forgotten. Your lungs are
burning. Your entire body is aflame. Even the Brambleheart is practically moaning, withering before your very eyes. The amount of prana Lancer was draining didn't even compare to Rider even when Rider was using both of his Noble Phantasms.
With absolute certainty, you know you're going to die if this keeps up for much longer.
Out of the corner of your eyes, you see Accolon and pieces of homunculi fly out of the room. You can't see Caster's face, but she's silent.
There is a small moment of quietness. The burning isn't so bad now, but the amount of prana Lancer was draining even by simply walking was making your insides churn.
Silver greaves stop by your face, and she kneels down. A cold gauntlet caresses your face warmly. "I ask of you, are you my Master?"
Your throat hadn't been pierced either. You shudder, gasping for air, "Y-ye-s. L-Lanc-"
[ ] "S-Sav-e A-Alice-"
[ ]
"K-k-ill C-aster."
Yes, only one option requires a CS - since it also happens to include the other in itself.
[X] 'Not a lot of options' is not the same as no options at all. Rider didn't give his life so you could simply surrender now.
I wonder if recalling Menw would have actually helped the situation at all?
Well, it would've had a better chance of saving Menw himself, but generally the outcomes of the last few posts built up to this point.
I'd like to mention that this was essentially the mid-story darkest moment, equivalent to Berserker killing Archer in Fate, or Shirou losing Saber in UBW and HF. But the
actual Holy Grail War starts now.
