Silence was their greatest enemy. Though thoughts and words could occasionally hurt them, the silence caused more damage. The world of the Maeroksigne, the world they knew, was built around the unspoken word. Life was created and kept going because of the words that filled the minds of every being on Earth, whether they were Maeroksigne, human, or animal. Their thoughts allowed life to thrive. Words were the epitome of life. The paints on the canvas. The notes to the song.
Silence was the exact opposite of it all. Like an empty cave, hollow and holed out and bare of any and all signs of intelligent existence, past or present. Life without words was not only dull, but unsatisfying and painful. Anyone could survive easily without ever uttering a single syllable aloud; it was the tacit words that meant the most. The words that never met the ear, but the mind; the heart. Without those words, life could not thrive.
