A beautiful singing voice echoes across the halls of the manor, the melodious notes filling the air. From some hidden corner, you sense the presence of a talented opera singer, practicing arias while they wait for their performance time. Perhaps the time is near, and they will soon put their talents on display. The hauntingly beautiful melody continues, each note flowing like silk to your ears. You get the sense that there is more than mere practice going on here. Is the opera singer perhaps expressing a deep emotion; Wether it would be anger or sadness?
