[Kaname Housen, Basement/Worm Pit, Matou Household]

It took a bit of time, but after several birds, a few precise angle measurements, and some pushing back of collapsed worm piles, Kaname finally finished throwing together his little summoning array. 

But did he really have to do this? He was only participating because he was told to, after all. There was still a chance to back down and [i]not[/i] risk his life. But he'd learned his lesson already. 

And that meant he had to say the words.

"Silver and iron to the origin.
Gem and the archduke of pacts to the foundation.
Let the descending winds become a wall. 
Let the gates in four directions close, rising above the crown, and let the three-forked road leading to the kingdom rotate.

Shut (fill). Shut (fill). Shut (fill). Shut (fill). Shut (fill).
Five perfections for each repetition.
And now, let the filled sigils be annihilated in my stead!

—Set.
Let thy body rest under my dominion, let my fate (doom) rest in thy blade.
If thou submittest to the call of the Holy Grail and if thou wilt obey this will and reason, then answer my summoning!

—I make my oath here. 
I am the person who is to become the virtue of all Heaven.
I am that person who is covered with the evil of all Hades.

Thou seven heavens, clad in a trinity of words, 
come past thy restraining rings,
O keeper of the balance—!”

His hand was thrust out, back of the palm burning as his bruise became a three-part Seal. Light and wind coursed around the summoning circle, illuminating the basement and sending crusty worm skins everywhere. 

And at the apex, the room went white.
