Siegfried walked up to the box and took out the artifact he had requested. He would have preferred to locate it himself, but the timing hadn't been ideal. It was a piece of petrified wood, with little significance to someone who didn't know its origin. However, this particular bit of wood was from the legendary hall Heorot, the dining place of many ancient Saxon heroes, but connected to one in particular. He briefly cast a look over the other two mages, then turned away. "I'll be in the basement," he said over his shoulder, a curt tone sounding through his deep, somewhat gravelly voice. Siegfried made his way down to the basement and withdrew a vial of mercury from within his coat. That's a perk, I guess. I don't care to explain to non-mages what I need this for.
Drawing the summoning circle came easily to him. It was not dissimilar to a few of the runes he used regularly, though he wouldn't have even attempted something of this magnitude without the Grail's assistance. It didn't take long; he had studied and practiced drawing the circle to ensure he didn't muck anything up. After he was done, he placed the timber and began the chant.
Fill. Fill. Fill. Fill. Fill.
Let it be filled fivefold for every turn, simply breaking asunder with every filling.
For the essence, silver and steel.
For the foundation, stone and the archduke of contracts.
Close the gates of the four cardinal directions.
Come forth from the crown, and follow the three forked road leading to the kingdom.
Let it be declared now.
My will creates your body.
Your sword creates my destiny.
If you heed the Grail's call and obey my will and reason, then answer me.
I hereby swear.
That I shall be all the good in the world.
That I shall defeat all evil in the world.
From the seventh heaven, clad in the three great words of power,
come forth from the circle of binding, guardian of the scales!
As he spoke, the silvery fluid on the floor began to glow brighter and brighter with an internal light, rising to a magnitude that was almost blinding to look at. With the last line, there was a flash, and the wood in the center of the circle had been replaced by a tall, muscle-bound man with dark, raggedly cut hair and a simple chestplate that appeared to be made of iron, with accompanying greaves and trousers. His shirt had no sleeves, showcasing the immense power held in his arms. At his belt was an ornate scabbard containing a sword, contrasting with the rest of his outfit. The Servant wore an amulet in the shape of the hilt of a sword, and beyond that no other decoration. The man looked down at Siegfried (a bit unsettling, since Siegfried was considered fairly tall himself) and spoke. "Are you my Master?"
"Indeed, I am the one that summoned you, King of the Geats. Together, we will seek the Grail, and crush our enemies before they have a chance to bend it to their own ends." Both of them looked the other over. Siegfried smiled. Saber - better known as Beowulf - had all of the overwhelming strength he had possessed in his legend. "We have much to do before we engage in combat." Saber nodded, and faded away into spirit form.
