Soter

is the third Noble Phantasm of Ptolemy.
Strictly speaking, it is not a distinct Noble Phantasm, but a double fusion Noble Phantasm of Bibliotheca Basileus and Pharos Tis Alexandreias.
The information of the Atlas Institute, which lies in Bibliotheca Basileus, is converted into magical light and released by Pharos Tis Alexandreias.
Crystalline trees entwine all over Ptolemy's body, immobilizing him. The trees then create several crystalline lenses to further magnify the light, turning the servant into a piece of artillery.
The light, which arises from the lore of the Great Library of Alexandria burning down for the last time, is essentially the same light as that of the Beast that incinerated human history. However, as can be seen from the premise, the use of this treasure makes access to the Bibliotheca Basileus impossible, destroying even Pharos Tis Alexandreias, and also shattering the spiritual core of Ptolemy itself. In other words, it is a triple Broken Phantasm.
"Soter" is Ptolemy's second name, meaning "savior", "redeemer", or "protector". It is at that moment, when everything and anything of the wisdom that has been guarded with all one's being is burned away, that true salvation appears.
