Eiro looked within himself and concentrated on the Sensory Homunculus in his mind that he created as a representation for his Five of Pentacles, the <Ultimate Perception>. And to signify the process of deactivating the card... He made the Homunculus go to sleep. It curled up on the ground and dozed off, and as if its existence faded away slowly as it slept, Eiro's world seemed completely empty for a moment.
Absolute silence, not a single scent, no vibrations or even the touch of the ground he was sitting on could be felt.
It was an instant of absolute sensory deprivation that Eiro had never experienced before. And a few moments later, Eiro's senses returned to an extent. Dulled, weakened. This was what Eiro's senses were supposed to be like without the boost of the Five of Pentacles.
