(Juxta Military Base, Prison Cell, Leo's POV)
After killing about two dozen prisoners, Leo finally felt like his tattoo could not hold any more essence, and hence he paused with his killing and focused on utilising it instead.
Sitting cross-legged on the cold prison floor, he placed his blood-stained dagger beside him and shut his eyes, allowing the residual screams of the dead to fade into silence.
The tattoo on his back pulsed faintly, as though eager to release its harvest, while Leo himself focused on guiding it gently, as he circulated it along the tattoo'd pathways.
He sent the first streams of gray fog upward, behind his eyes, where he pooled mana on the regular to sharpen his ability to perceive aura.
The sensation was strange, like pouring liquid fire directly into his vision, but instead of pain there was clarity.
Threads of intent began to unravel before him, as suddenly, threads of maroon, blue, red and blue burst before him.
