Schrift

A is the name given to the epithet corresponding to each Sternritter's particular ability.

Overview
When promoted to the ranks of Sternritter, a Quincy of the Wandenreich undergoes a ceremony called the Initial-In-Soul Writing Ritual. The basis of this ritual involves the Quincy in question drinking a cup of Yhwach's blood, after which Yhwach is able to write an initial of the power he wishes to bestow on 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.

Trivia
General Trivia= Klub Outside Trivia=
 * 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.
 * According to Q&A #281 by Tite Kubo on his fansite "Klub Outside", Yhwach can see in advance which Schrift a chosen Quincy would recieve on their soul, and thus selects Quincy to empower based on those criteria, both concerning the power and which letters are unaccounted for.
