Grutrissheit

Grutrissheit (グルトリスハイト, Gurutorisuhaito) is the name of Mestionora's bible, as well as man-made transcription of the divine book. According to legend, it is the original bible that the first king of the country was permitted to transcribe upon being chosen by the Gods. Therefore, it is the symbol of power for all Zents.

Presumably all other Bibles have been derived from this transcription by the first king.

Due to being founded by a former Yurgenschmidt prince, who had already obtained a Grutrissheit of his own, by the time his brother was chosen as the successor, the country of Lanzenave likewise has a Grutrissheit as the symbol of it's king, which is passed down by the royal family through the generations.

Like all other Divine Instruments, nobles of sufficient skill, mana capacity and knowledge can turn their schtappe into a copy of the Grutrissheit, by chanting a spell of the same name. In fact it appears like many Zents of the past only possessed such a morphed variant of the Grutrissheit, rather than a physical transcription made of paper and ink.

Unlike the other Divine Instruments however, the such a schtappe turned Grutrissheit does not necessarily have to take on the same appearance as the original and can be altered to fit the user's preferences. In extreme cases, this can even mean it no longer takes the shape of a book at all, like when Rozemyne turned her Grutrissheit into a modern day touch-screen tablet, complete with search function.

Apart from the obvious function of containing religious stories and prayers and being the symbol of office for the king, the Grutrissheit that are passed down from the Zent to their successors are also magic tools that are integral for interacting with the foundational magic of the country of Yurgenschmidt. Among other things, it is necessary to have a Grutrissheit to redraw duchy borders, destroy or create duchy foundations and the opening and closing of the country gates.

Like with the Divine Instruments, a sufficiently skilled mana wielder is able to morph their schtappe into a duplicate of a Grutrissheit. It has been confirmed that at last some of the past Zents only had such a schtappe-morphed duplicate, rather than a physical transcription of Mestionora's holy book, albeit it is unclear whether they were the exception or the rule. Naturally any such schtappe duplicate disappears upon the death of the owner.

In the ancient past, it was tradition for each Zent to make their own transcription directly from the first one that the first king had transcribed directly from Mestionora's bible. Over time, however, this changed to the successor copying their father's transcription, rather than the original Grutrissheit.

During the ravages of the last civil war, the bible written by the previous king was lost. In theory, it is now the duty of the current Zent Trauerqual to make a new transcription from the original Grutrissheit of the first king, but unfortunately, its location is currently unknown.

Ferdinand of Ehrenfest speculates in private that its location has been passed down from kings to successors only orally. Since the current king was originally raised as a vassal to his older brothers and only became king due to exceptional circumstances, he never received this knowledge, leaving him unable to fulfill this duty.

In the course of her translations of the texts in the Underground Archive Rozemyne discovers hints, that the path to the Grutrissheit is connected to the Shrines scattered that can be found on the academy grounds. This is confirmed, when Prince Anastasius takes her to one of the shrines, where Rozemyne inadvertedly obtains a feystone tablet, granting her part of the key to Mestionora's book. Emboldened by this, Anastasius has Rozemyne acquire the entire set, at which point a previously hidden door within the underground archive becomes accessible to her. However Rozemyne is unable to reach the location that presumably holds physical Grutrissheit, due to a magical barrier that only allows people entry, who are registered with the royal family.

During her fourth year at the Royal Academy, Lady Rozemyne is able to fulfill the qualifications to become Zent and thus is summoned to Erwaermen to have the information making up the Grutrissheit sent directly into her mind, which enables her to turn her schtappe into her own version of the holy book. However, when the process is complete, she holds only something between 60 and 70 percent of the total knowledge. As it turned out, ten years earlier Ferdinand somehow forced his way into the process, but broke it off when only part of the information had been loaded into his mind. Furthermmore, due to a row of unlikely events, Rozemyne had ended up dyed in Ferdinand's mana for an unusually long time, which resulted in Erwaermen, who is only able to see mana, being unable to differentiate her signature from that of Ferdinand, which means that to the gods and to magic tools, the two essentially count as the same person and thus their Grutrissheit is now split between them. Erwaermen tasks Rozemyne to kill Ferdinand and absorb his feystone, to complete her bible and become a true Zent, but Rozemyne vehemently opposes the notion.

Despite only having an incomplete Grutrissheit, Rozemyne is still able to summon it by transforming her schtappe. Her version of Mestionora's book takes the shape of a modern day tablet.
