Fate/Grand Shenanigans: Chaos in Camelot

Lion and Wolf

The lion king faced down the knight of wolves as the two held their weapons at the ready.

Y/n stood with his new sword, Bheathach Siorruidh, at the ready while the lion king held Rhongomyniad poised to deliver a fatal blow. Despite her apparent readiness, the lion king could absolutely not underestimate Y/n. The sword he now wielded was a fusion of his own power and that of Excalibur.

She lowered her head and charged at full speed towards the knight of wolves, who graciously stepped to one side before slashing downwards. The others' eyes widened as the slash produced a sound similar to a wolf's howl.

The lion king spun and went for another strike, only to have it parried by the new sword.

Y/n smirked as he clashed again and again with the lion king.

As the two fought, the Hassans and Gawain joined them with Lordred, Arcueid and Shinbei.

Lordred: "The hell kinda sword is that!?"

Hassan: "A blade born with the name eternal beast. Thou would do well to carve its name into thy spirit origin."

Gawain: "That aura... Excalibur?"

???: "It was once the sword of promised victory. The blade now in Y/n von Einzbern's hands is the sword of the eternal oath."

The group looked up and saw Isis descending with the other Egyptian gods and servants upon Ra's sun barge.

Isis stepped down from the barge as Y/n kept his attention on the fight.

Isis: "Taking up that sword has solidified his existence as the Beast of eternity. However this is a new existence for the beasts."

Hassan: "Thou senses it too."

Sekhmet: "So this beast ain't an evil of humanity?"

Isis: "Quite the opposite."

Sherlock: "Indubitably. What we are bearing witness to is a beast born not of humanity's evil, but of humanity's potential."

Iskandar: "HAHAHA! If I had known this young man would be such a being I would ask him to join my army! However, I will not."

Sherlock: "Oh? And why might that be?"

Iskandar: "Because a king does not submit to any other."

Sherlock smiled as he turned back to the battle as it raged on, the holy light of Rhongomyniad clashed with the primeval gleam of Beathach Siorruidh.

The lion king threw everything she had into every attack, yet it was parried expertly by Y/n.

Y/n: "Y'know. This reminds me of when I used to spar with Leonidas."

The lion king had no interest in small talk, yet she listened anyway.

Y/n: "He taught me how to properly use a sword. How to fight with a spear. How to effectively use a bow. Everything I know about using the weapons I do can be traced back to my training with Leonidas. But there was one thing that neither he, nor anyone else could teach me."

The lion king thrust her lance forward as Y/n used his shin armour to kick the lance away.

Y/n: "I was the one who had to first learn how my power worked. This is no different. But I may as well start learnin' now!"

Y/n slashed upwards and knocked the lion king off balance before he held the sword in a stabbing position.

Y/n: "Exhaust the concept of annihilation. Exhume the concept of death..."

Y/n shut his eyes as the blade began to glow a brilliant light blue while the wind kicked up around the tower at the end of the world.

Y/n: "... Go forth and inflict devastation. BEATHACH SIORRUIDH!!"
