Eins

For the elements, silver and iron. For the foundation, stone and the Archduke of Pacts. And for the ancestor, my great master, Schweinorg. Close the gates of the four directions. Come forth from the Crown and follow the forked road leading to the Kingdom. Fill, fill, fill, fill, fill. Repeat five times. When each is filled, destroy it. Set.

Heed my words. My will creates your body, and 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. Thou Seventh Heaven, clad in the three great words of power, come forth from the circle of binding, Guardian of the Scales!

[This is a master (haha) post for Fate/PSLs! If you need anything specific tailored to your character (like a starter that doesn't start with the summoning like the above) let me know! We'll work something out over PM or Plurk.]
