Something something Quintessence being the power of spirit/souls, although Quintessence ghouls have been in the clergy for as long as the other elemental ghouls, little is known about their powers, and what is known is usually through experiential learning. They can manipulate the soul through the mind and feel the intense feelings of others. No one knew of one of their other abilities until after the 3 Emeritus brothers were murdered.
While the rest of the clergy was busy celebrating the coming of a new pope all of the previous ghouls went into a long mourning period, none of them left the den, and when Dew and Aether had to be dragged out by Sister Imperator herself to meet the new papa and start practicing, everyone rioted. Omega felt restless after crying so many tears and decided it was finally time to leave the den in the dungeons of the abbey. The space had begun to feel oppressive, and grief hung heavy in the air.
The reality of all of it crashed down on Omega again as he stared at the empty graves of the emeritus brothers in the pale moonlight. He sank to the ground in front of the tombstones; he couldn't even muster up the energy to cry. He kept his head down, looking at his clenched fists, not wanting to stare at the reminder that they were gone.
Out of the very corner of his eye, he saw movement, it barely registered in his brain, too focused on the swell of emotions threatening to drown him. Something gnawed at the back of his mind, begging him to look up; it felt foreign, like it wasn't his own thoughts. He couldn't help but look up.
There standing before him was Terzo, it couldn't be but he knew it was. He had those same kind, mismatched eyes, the same slightly crooked smile, the same face. He was almost the same as the day Omega lost him, but he was paler and slightly translucent.
"God, I must be losing it," Omega whispered out, voice rough from crying and disuse.
The figure chuckled sadly, "Last time I checked, you didn't believe in God, mio tesoro."
Omega got up and ran towards the man and tried to capture him in an embrace. He sobbed when all he felt was cold air instead of the warm hug he so desperately needed.
"Oh Meg, I wish I could hug you too, but I'm so glad you can at least see me, I was starting to think nobody could," Terzo whispered. "At least this cruel world has allowed me the comfort of still having you."
