The book on the table starts by describing (and tabulating) how the garrison received many relics to keep in hiding. This happened soon after the decades-long civil war ended between on the one hand the Council of Apostles and on the other hand forces loyal to Emperor Heideran V and the lords of the Privy Council. The Tetrimon had chosen the losing side, the side of the Apostles, but not openly. Their grand-master, Tetrimon IV, secured the relics that were held by the Council of Apostles, and hid them in places such as the vault here in Mezagorm. This book is important proof of that crime.
Enter the Theology Council. The Theology Council was installed by Emperor Heideran V to replace the Council of Apostles. Its first task was to remove from scripture all the heresies of the Apostles. But its inquisitors were also hunting for lost relics.
The book writes that in the summer of 21948, a Theology Council fleet was on its way to Shastal, bound for Mezagorm.
Now we know that the Theology Council inquistors had no idea about a Tetrimon cache here. They came to Mezagorm to look for old scripture. After the death of Zaragram, the Council of Apostles became very powerful and changed scripture to cement their power. To undo this and show that the Apostles usurped scripture would further justify and glorify the efforts of Emperor Heideran V.
However, the garrison did not know that, and they thought that the inquisitors had found out about the hiding place. They panicked that it was no longer safe. In a hurry, they moved most items, including unfortunately the Ink of Truth (denoted by its code AVSAP in the tables of outgoing relics). It has new codes for other hiding spaces, but that will require more intensive study, and a comparison to the book I found in Baron Redwolfe's library.
However, they did not take everything in their hurried flight - they had to leave behind a particular relic, the legion of Ves-Udor. That is no doubt what lies in the closed lockers.
