Overview
When promoted to the ranks of Sternritter, a Quincy of the Wandenreich undergoes a ceremony called the, involving the Quincy in question drinking a cup of Yhwach's blood, after which Yhwach is able to carve an initial of the power he wishes to bestow directly into the select individual's soul. In addition, the granted power returns to Yhwach should the Sternritter die.

History
Yhwach had the ability to share part of his soul with other Quincy to empower them from when he was born. At some point in his later life, Yhwach discovered how to improve upon this ability and thus grant unique powers to other Quincy. Lille Barro was the first Quincy to ever be bestowed a Schrift by Yhwach.

 * In the original release of Chapter 646, Lille says he is the last Quincy to be given a Schrift. It was changed to first Quincy in Chapter 656. The Japanese release of Volume 71 corrected 646 and changed it to first; however, the official English release of Volume 71 keeps the mistake.
 * Despite being ranked amongst the Sternritter, Pernida Parnkgjas and Gerard Valkyrie do not possess an actual Schrift, as they already had their powers before encountering Yhwach.
 * In Ryōgo Narita's short story Beginning of the Revive of Tommorow, Shaz Domino was assigned a letter, Ϛ or, by Yhwach more as an honorary designation than a genuine Schrift, in the same manner as Pernida and Gerard.
 * According to Q&A #281 by Tite Kubo on his fansite "Klub Outside", Yhwach can see in advance which Schrift a chosen Quincy would receive on their soul, and thus selects Quincy to empower based on those criteria, both concerning the power and which letters are unaccounted for.
