Cover art for Subtraction lyrics by Coheed and Cambria

Held in Evagria's embrace, Sirius reflects upon his choice to leave Meri to pursue this dream of discovering the nature of the Keywork. In this moment of clarity, he realizes that, while he embarked on this mission to further humanity's collective scientific knowledge, he also had a burning, selfish desire to prove himself better than his peers and to make Meri proud.

The reality was, of course, that he did not need to go to such lengths to make her proud because there was never a time that she thought poorly of him. In his quest to gain approval, he ended up separating himself from the thing that mattered most in his life.
