I never felt sleepy, or hungry, or tired.
My steps were always light.
In fact, now, I felt even stronger than I had before. There was a strange sense of strength filling me up after I had 'consumed' the soul of the wolf.
I thought of many reasons it could be happening, but my head was still mostly blank. Nothing I saw around myself felt special, it was all recognizable yet very unfamiliar.
There was something new and different though. Something that truly amazed me, like an experience very fresh.
My sense of smell, sight, and hearing had shot up to an inane degree.
How did a soul even see, or hear, or smell? I didn't know that just yet.
But I could make some conjectures.
For now, after seeing the wolf that I had killed, I could deduce that my senses only gathered the same sounds made by the souls.
To further test it, I tried to throw some rocks at the walls of the cave, but it did not make any noise.
